RE: [Xen-devel] kernel BUG at arch/xen/i386/mm/hypervisor.c:354, (xen_create _contiguous_region)!
This is believed fixed, at least in the staging tree. It was introduced as a result of the change to avoid the alignment problem introduced by setting CONFIG_DEBUG_SLABALLOC=y in Fedora kernels. Pretty much all the bugs that have been filed today are different incarnations of this issue. It''s quite interesting in that it''s the first example of a regression that survived the mini-XenRT test run but blew up badly on the long overnight run. It was probably fixed before anyone in the US woke up, but there was a backlog in the staging tree... [see the xenrt web page for the full horror of last nights run!] Ian> http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=395 > > The guest domain crashed during the routine daily tests that I ran. > > Machine: IBM ThinkCentre, 1GB of RAM with FC3 based setup. > > Xen build, PAE enabled using changeset: 7701:abbe3df33774 > > [root@thinkcentre-dom0 xen-unstable.hg]# cat /proc/cpuinfo > processor : 0 > vendor_id : GenuineIntel > cpu family : 15 > model : 3 > model name : Intel(R) Pentium(R) 4 CPU 3.00GHz > stepping : 4 > cpu MHz : 2992.638 > cache size : 1024 KB > fdiv_bug : no > hlt_bug : yes > f00f_bug : no > coma_bug : no > fpu : yes > fpu_exception : yes > cpuid level : 3 > wp : yes > flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov > pat pse36 > clflush > dts acpi mmx fxsr sse sse2 ss ht tm pbe pni monitor ds_cpl cid xtpr > bogomips : 5976.88 > > Problem: > > kernel BUG at arch/xen/i386/mm/hypervisor.c:354 (xen_create > _contiguous_region)! > Ä<c011847b>Ü xen_create_contiguous_region+0x2eb/0x360 > Ä<c026761e>Ü net_rx_action+0x13e/0x220 > Ä<c01072d9>Ü skbuff_ctor+0x69/0x70 > Ä<c014d965>Ü cache_init_objs+0x55/0x90 > Ä<c014db8c>Ü cache_grow+0x13c/0x240 > Ä<c014deb6>Ü cache_alloc_refill+0x226/0x260 Ä<c014e14c>Ü > kmem_cache_alloc+0x9c/0xb0 Ä<c02601cd>Ü > alloc_skb_from_cache+0x4d/0x100 Ä<c01071cb>Ü > alloc_skb+0x9b/0xc0 Ä<c025ee90>Ü > sock_alloc_send_pskb+0xc0/0x1d0 Ä<c025efcd>Ü > sock_alloc_send_skb+0x2d/0x40 Ä<c02aff19>Ü > unix_stream_sendmsg+0x199/0x470 Ä<c02c52a2>Ü > schedule+0x3f2/0x780 Ä<c025be31>Ü sock_aio_write+0x101/0x120 > Ä<c01778df>Ü pipe_wait+0x8f/0xb0 Ä<c0169c39>Ü > do_sync_write+0xc9/0x110 Ä<c0177c0a>Ü pipe_readv+0x2ba/0x360 > Ä<c0139200>Ü autoremove_wake_function+0x0/0x60 Ä<c0199c9a>Ü > dnotify_parent+0x3a/0xe0 Ä<c0177ce8>Ü pipe_read+0x38/0x40 > Ä<c0169d2c>Ü vfs_write+0xac/0x160 Ä<c0169eb1>Ü > sys_write+0x51/0x80 Ä<c010a1e9>Ü syscall_call+0x7/0xb Kernel > panic - not syncing: BUG! > > -- > Regards, > > David F Barrera > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
