[Xen-devel] kernel BUG at arch/x86/xen/mmu.c:1649! and others ...
Hi Jeremy, I''m still experiencing total freezes of my system when passing through a device, and with most linux kernel debug options on in the guest i still don''t see a oops. I do get these messages in dom0 on boot, although perhaps they are false due to all the debug enabled. For the freeze, i have enabled debug in xen, in xend config, put the on_crash for the guest on preserve. But still it freezes with this domU, all others just run fine, when i don''t do pci-passthrough it also runs fine. I looked at the source of xen-swiotlb, but didn''t see any debug i could enable there. -- Sander [ 0.040000] ------------[ cut here ]------------ [ 0.040000] WARNING: at arch/x86/xen/enlighten.c:742 xen_apic_write+0x15/0x17() [ 0.040000] Hardware name: MS-7640 [ 0.040000] Modules linked in: [ 0.040000] Pid: 0, comm: swapper Not tainted 2.6.32.17+xen-next-2.6.32.x-20100807 #1 [ 0.040000] Call Trace: [ 0.040000] [<ffffffff81058602>] ? add_timer_on+0xc3/0xd1 [ 0.040000] [<ffffffff8100a811>] ? xen_apic_write+0x15/0x17 [ 0.040000] [<ffffffff8104a4ab>] warn_slowpath_common+0x77/0xa4 [ 0.040000] [<ffffffff8104a4e7>] warn_slowpath_null+0xf/0x11 [ 0.040000] [<ffffffff8100a811>] xen_apic_write+0x15/0x17 [ 0.040000] [<ffffffff8101e181>] perf_events_lapic_init+0x2e/0x30 [ 0.040000] [<ffffffff817a6918>] init_hw_perf_events+0x326/0x3c3 [ 0.040000] [<ffffffff814684f8>] ? identify_cpu+0x2ee/0x2f9 [ 0.040000] [<ffffffff817a6564>] identify_boot_cpu+0x3c/0x3e [ 0.040000] [<ffffffff817a65ce>] check_bugs+0x9/0x2d [ 0.040000] [<ffffffff8179dcbf>] start_kernel+0x38e/0x3a3 [ 0.040000] [<ffffffff8179d2bf>] x86_64_start_reservations+0xaa/0xae [ 0.040000] [<ffffffff817a09e5>] xen_start_kernel+0x62e/0x635 [ 0.040000] ---[ end trace 4eaa2a86a8e2da22 ]--- [ 12.646740] ------------[ cut here ]------------ [ 12.650932] kernel BUG at arch/x86/xen/mmu.c:1649!
