[Xen-devel] Warn/panics booting Konrad''s master tree under xen 4.1.1
Hi Konrad, I have tried your current master tree (commit 602d7a606974c54dc8bd61527c051d7d697a5f86) as domU (under xen 4.1.1 and a 2.6.32.35 dom0), that seems to work fine. I have tried to use the same kernel as dom0 as well, but i get the warns/panic below, when i boot the kernel bare metal it works ok. Complete serial log is attached, i have re-compiled with and without pv-spinlocks but there is no difference. Also xen-pciback compiled in, with xen-pciback.hide as kernel boot parameter doesn''t seem to seize the devices. -- Sander 4.531095] f7188[ 5.139554] R10: 0000000000000000 R11: 0000000000000001 R12: 00007fffffffd000 [ 5.139556] R13: ffff8800204d4000 R14: ffff880020007548 R15: 0000000020e09000 [ 5.139560] FS: 00007fc956118700(0000) GS:ffff88002f040000(0000) knlGS:0000000000000000 [ 5.139562] CS: e033 DS: 0000 ES: 0000 CR0: 000000008005003b [ 5.139564] CR2: ffff880020e0a000 CR3: 0000000001a4d000 CR4: 0000000000000660 [ 5.139566] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 5.139568] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 5.139570] Process init (pid: 1726, threadinfo ffff880020006000, task ffff8800231463c0) [ 5.139572] Stack: [ 5.139574] ffff880020007588 ffffffff811006c8 0000000000000000 0000000000000000 [ 5.139579] 0000000000000000 000000021a6ec675 0000000000000001 ffff880020007600 [ 5.139584] 0000000000000000 ffff8800204d4000 00007fffffffefff ffffffffffffffff [ 5.139589] Call Trace: [ 5.139592] [<ffffffff811006c8>] unmap_vmas+0x468/0x9f0 [ 5.139596] [<ffffffff81103a84>] exit_mmap+0xa4/0x150 [ 5.139600] [<ffffffff81007fa0>] ? xen_clocksource_read+0x20/0x30 [ 5.139603] [<ffffffff8104f41f>] mmput+0x4f/0xe0 [ 5.139607] [<ffffffff81053e01>] exit_mm+0x131/0x170 [ 5.139610] [<ffffffff81055c04>] do_exit+0x174/0x860 [ 5.139613] [<ffffffff81765eb0>] ? _raw_spin_unlock_irqrestore+0x40/0x80 [ 5.139617] [<ffffffff81051dda>] ? kmsg_dump+0x4a/0x100 [ 5.139620] [<ffffffff810080f2>] ? check_events+0x12/0x20 [ 5.139623] [<ffffffff8100f62d>] oops_end+0x9d/0xd0 [ 5.139627] [<ffffffff8103323b>] no_context+0xfb/0x260 [ 5.139630] [<ffffffff81004651>] ? pte_mfn_to_pfn+0x91/0xf0 [ 5.139633] [<ffffffff810334c5>] __bad_area_nosemaphore+0x125/0x1f0 [ 5.139638] [<ffffffff81004169>] ? __raw_callee_save_xen_pmd_val+0x11/0x1e [ 5.139641] [<ffffffff810335a3>] bad_area_nosemaphore+0x13/0x20 [ 5.139644] [<ffffffff81033ad5>] do_page_fault+0x2f5/0x490 [ 5.139648] [<ffffffff810080df>] ? xen_restore_fl_direct_reloc+0x4/0x4 [ 5.139652] [<ffffffff810e2173>] ? __alloc_pages_nodemask+0x113/0x720 [ 5.139657] [<ffffffff8133e1aa>] ? trace_hardirqs_off_thunk+0x3a/0x6c [ 5.139663] [<ffffffff817665c5>] page_fault+0x25/0x30 [ 5.139666] [<ffffffff8110016e>] ? __tlb_remove_page+0x9e/0xc0 [ 5.139670] [<ffffffff81100164>] ? __tlb_remove_page+0x94/0xc0 [ 5.139673] [<ffffffff8110086d>] unmap_vmas+0x60d/0x9f0 [ 5.139677] [<ffffffff81103a84>] exit_mmap+0xa4/0x150 [ 5.139680] [<ffffffff8104f41f>] mmput+0x4f/0xe0 [ 5.139683] [<ffffffff811271b6>] flush_old_exec+0x556/0x800 [ 5.139686] [<ffffffff8116f4a3>] load_elf_binary+0x323/0x1c60 [ 5.139690] [<ffffffff810fd813>] ? follow_page+0x393/0x4f0 [ 5.139693] [<ffffffff810fdff1>] ? __get_user_pages+0x191/0x620 [ 5.139697] [<ffffffff8116c6e9>] ? load_misc_binary+0x89/0x3c0 [ 5.139701] [<ffffffff810fe532>] ? get_user_pages+0x52/0x60 [ 5.139704] [<ffffffff8112638c>] ? get_arg_page+0x5c/0x100 [ 5.139707] [<ffffffff81126913>] search_binary_handler+0xd3/0x2e0 [ 5.139710] [<ffffffff8116f180>] ? elf_map+0x1d0/0x1d0 [ 5.139714] [<ffffffff8112853f>] do_execve_common+0x22f/0x2e0 [ 5.139717] [<ffffffff8111c212>] ? kmem_cache_alloc+0x72/0x150 [ 5.139720] [<ffffffff8112867a>] do_execve+0x3a/0x40 [ 5.139723] [<ffffffff8101551a>] sys_execve+0x4a/0x80 [ 5.139727] [<ffffffff817670bc>] stub_execve+0x6c/0xc0 [ 5.139729] Code: 0f 1f 84 00 00 00 00 00 55 48 89 e5 66 66 66 66 90 65 8b 04 25 50 dc 00 00 85 c0 75 0e 65 c7 04 25 50 dc 00 00 01 00 00 00 c9 c3 <0f> 0b eb fe 66 0f 1f 84 00 00 00 00 00 55 48 89 e5 53 66 66 66 [ 5.139783] RIP [<ffffffff8102fe33>] paravirt_enter_lazy_mmu+0x23/0x30 [ 5.139787] RSP <ffff880020007448> [ 5.139789] ---[ end trace 09caa95ef9593519 ]--- [ 6.455861] udlfb: Reallocating framebuffer.

I do have the xen-pciback lines in grub (exactly the same as for the 2.6.32.35 kernel, except for the xen-pciback.passthrough=passthrough parameter because with 2.6.32.35 you specify it at compile time ), but it seems no device gets seized by pciback some how. grub lines: menuentry '' XEN 4.1.1 Debian GNU/Linux, with Linux 3.0.0-xen-3.1-konrad-master-20110722+'' --class debian --class gnu-linux --class gnu --class os --class xen { insmod part_msdos insmod ext2 set root=''(hd0,msdos1)'' search --no-floppy --fs-uuid --set b45b2279-dbde-4808-b9ec-4745e598c8d2 echo ''Loading Linux 3.0.0-xen-3.1-konrad-master-20110722+ ...'' multiboot /xen-4.1.1.gz dom0_mem=768M loglvl=all loglvl_guest=all console_timestamps vga=gfx-1280x1024x32 cpuidle cpufreq=xen noreboot debug lapic=debug apic_verbosity=debug apic=debug acpi_enforce_resources=lax iommu=on,amd-iommu-debug amd_iommu=on amd-iommu-debug com1=115200,8n1 console=vga,com1 module /vmlinuz-3.0.0-xen-3.1-konrad-master-20110722+ root=/dev/mapper/serveerstertje-root ro console=hvc0 console=tty console=vga nomodeset vga=794 video=vesafb earlyprintk=xen max_loop=255 loop_max_part=63 acpi_enforce_resources=lax xen-pciback.passthrough=passthrough xen-pciback.hide=(03:06.0)(04:00.0)(04:00.1)(04:00.2)(04:00.3)(04:00.4)(04:00.5)(04:00.6)(04:00.7)(0a:00.0)(0a:00.1)(0a:00.2)(0a:00.3)(0a:00.4)(0a:00.5)(0a:00.6)(0a:00.7)(05:00.0)(05:00.1)(07:01.0)(07:01.1)(07:01.2) pci=resource_alignment=07:01.0\;07:01.1\;07:01.2 echo ''Loading initial ramdisk ...'' module /initrd.img-3.0.0-xen-3.1-konrad-master-20110722+ } menuentry '' XEN 4.1.1 Debian GNU/Linux, with Linux 2.6.32.35-xen-next-2.6.32.x-20110325'' --class debian --class gnu-linux --class gnu --class os --class xen { insmod part_msdos insmod ext2 set root=''(hd0,msdos1)'' search --no-floppy --fs-uuid --set b45b2279-dbde-4808-b9ec-4745e598c8d2 echo ''Loading Linux 2.6.32.35-xen-next-2.6.32.x-20110325 ...'' multiboot /xen-4.1.1.gz dom0_mem=768M loglvl=all loglvl_guest=all console_timestamps vga=gfx-1280x1024x32 cpuidle cpufreq=xen noreboot debug lapic=debug apic_verbosity=debug apic=debug acpi_enforce_resources=lax iommu=on,amd-iommu-debug amd_iommu=on amd-iommu-debug com1=115200,8n1 console=vga,com1 module /vmlinuz-2.6.32.35-xen-next-2.6.32.x-20110325 root=/dev/mapper/serveerstertje-root ro nomodeset vga=794 video=vesafb earlyprintk=xen max_loop=255 loop_max_part=63 acpi_enforce_resources=lax xen-pciback.hide=(03:06.0)(04:00.0)(04:00.1)(04:00.2)(04:00.3)(04:00.4)(04:00.5)(04:00.6)(04:00.7)(0a:00.0)(0a:00.1)(0a:00.2)(0a:00.3)(0a:00.4)(0a:00.5)(0a:00.6)(0a:00.7)(05:00.0)(05:00.1)(07:01.0)(07:01.1)(07:01.2) pci=resource_alignment=07:01.0\;07:01.1\;07:01.2 echo ''Loading initial ramdisk ...'' module /initrd.img-2.6.32.35-xen-next-2.6.32.x-20110325 }>> [ 5.139589] Call Trace: >> [ 5.139592] [<ffffffff811006c8>] unmap_vmas+0x468/0x9f0 >> [ 5.139596] [<ffffffff81103a84>] exit_mmap+0xa4/0x150 >> [ 5.139600] [<ffffffff81007fa0>] ? xen_clocksource_read+0x20/0x30 >> [ 5.139603] [<ffffffff8104f41f>] mmput+0x4f/0xe0 >> [ 5.139607] [<ffffffff81053e01>] exit_mm+0x131/0x170 >> [ 5.139610] [<ffffffff81055c04>] do_exit+0x174/0x860 >> [ 5.139613] [<ffffffff81765eb0>] ? _raw_spin_unlock_irqrestore+0x40/0x80 >> [ 5.139617] [<ffffffff81051dda>] ? kmsg_dump+0x4a/0x100 >> [ 5.139620] [<ffffffff810080f2>] ? check_events+0x12/0x20 >> [ 5.139623] [<ffffffff8100f62d>] oops_end+0x9d/0xd0 >> [ 5.139627] [<ffffffff8103323b>] no_context+0xfb/0x260 >> [ 5.139630] [<ffffffff81004651>] ? pte_mfn_to_pfn+0x91/0xf0 >> [ 5.139633] [<ffffffff810334c5>] __bad_area_nosemaphore+0x125/0x1f0 >> [ 5.139638] [<ffffffff81004169>] ? __raw_callee_save_xen_pmd_val+0x11/0x1e >> [ 5.139641] [<ffffffff810335a3>] bad_area_nosemaphore+0x13/0x20 >> [ 5.139644] [<ffffffff81033ad5>] do_page_fault+0x2f5/0x490 >> [ 5.139648] [<ffffffff810080df>] ? xen_restore_fl_direct_reloc+0x4/0x4 >> [ 5.139652] [<ffffffff810e2173>] ? __alloc_pages_nodemask+0x113/0x720 >> [ 5.139657] [<ffffffff8133e1aa>] ? trace_hardirqs_off_thunk+0x3a/0x6c >> [ 5.139663] [<ffffffff817665c5>] page_fault+0x25/0x30 >> [ 5.139666] [<ffffffff8110016e>] ? __tlb_remove_page+0x9e/0xc0 >> [ 5.139670] [<ffffffff81100164>] ? __tlb_remove_page+0x94/0xc0 >> [ 5.139673] [<ffffffff8110086d>] unmap_vmas+0x60d/0x9f0 >> [ 5.139677] [<ffffffff81103a84>] exit_mmap+0xa4/0x150 >> [ 5.139680] [<ffffffff8104f41f>] mmput+0x4f/0xe0 >> [ 5.139683] [<ffffffff811271b6>] flush_old_exec+0x556/0x800 >> [ 5.139686] [<ffffffff8116f4a3>] load_elf_binary+0x323/0x1c60> .. snip..

Weird it works for me. Let me double check just to make sure. And I believe I''ve the kworld usb video capture device so I should be able to reproduce this. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
