Interesting, I'll test ASAP, meanwhile please verify if a 2.6.16 guest kernel works fine at least on 2.6.15 host (as it does here). So we'll know that the semi-random segfault is a bug in 2.6.17-rc guests. I've built all 2.6.16-rc releases to start doing binary search to insulate where was the host change. > Initializing random number generator...done. > INIT: Entering runlevel: 2 > INIT: PANIC: segmentation violation! sleeping for 30 seconds. > [42949380.750000] BUG: failure at > /usr/src/linux-2.6.17-rc4/include/linux/elfcore.h:95/elf_core_copy_regs()! > [42949380.750000] Kernel panic - not syncing: BUG! > [42949380.750000] > [42949380.750000] Modules linked in: > [42949380.750000] Pid: 444, comm: init Not tainted 2.6.17-rc4 > [42949380.750000] RIP: 0033:[<0000000040145896>] > [42949380.750000] RSP: 0000007f7f811f30 EFLAGS: 00000246 > [42949380.750000] RAX: 0000000000000000 RBX: 0000000040017600 RCX: > ffffffffffffffff [42949380.750000] RDX: 0000000000000000 RSI: > 0000007f7f811f48 RDI: 0000000000000002 [42949380.750000] RBP: > 0000000000000000 R08: 00000000000001bc R09: 000000000000000b > [42949380.750000] R10: 0000000000000008 R11: 0000000000000246 R12: > 0000000000000002 [42949380.750000] R13: 00000000005096bc R14: > 0000000000406b21 R15: 0000000000406b21 [42949380.750000] Call Trace: > [42949380.750000] 67efb768: [<6001a10a>] panic_exit+0x2a/0x50 > [42949380.750000] 67efb778: [<60044acc>] notifier_call_chain+0x1c/0x30 > [42949380.750000] 67efb798: [<600348cf>] panic+0xcf/0x170 > [42949380.750000] 67efb7b8: [<600c336f>] ext3_mark_iloc_dirty+0xf/0x20 > [42949380.750000] 67efb7f8: [<600c7000>] ext3_orphan_del+0x1d0/0x280 > [42949380.750000] 67efb808: [<600c3528>] ext3_dirty_inode+0x78/0xa0 > [42949380.750000] 67efb838: [<6009d1c2>] __mark_inode_dirty+0x102/0x1b0 > [42949380.750000] 67efb848: [<600285b4>] set_signals+0x14/0x30 > [42949380.750000] 67efb858: [<600742c8>] kmem_cache_alloc+0x48/0x70 > [42949380.750000] 67efb878: [<600aa4e4>] elf_core_dump+0x264/0x2f0 > [42949380.750000] 67efb938: [<6007554d>] do_truncate+0x5d/0x70 > [42949380.750000] 67efb9a8: [<600842e7>] do_coredump+0x2c7/0x370 > [42949380.750000] 67efba48: [<60040bd9>] recalc_sigpending+0x19/0x20 > [42949380.750000] 67efba58: [<60041064>] __dequeue_signal+0x84/0xf0 > [42949380.750000] 67efbad8: [<600432e3>] get_signal_to_deliver+0x3e3/0x400 > [42949380.750000] 67efbb68: [<60065b6d>] __handle_mm_fault+0x23d/0x280 > [42949380.750000] 67efbb88: [<6013f13e>] __up_read+0x1e/0xc0 > [42949380.750000] 67efbbe8: [<60017866>] kern_do_signal+0x86/0x230 > [42949380.750000] 67efbc00: [<6001b370>] copy_chunk_from_user+0x0/0x40 > [42949380.750000] 67efbc18: [<600197cb>] segv+0x21b/0x300 > [42949380.750000] 67efbcb8: [<6002b8f8>] wait_stub_done+0x58/0x110 > [42949380.750000] 67efbce8: [<600434de>] sys_rt_sigprocmask+0x7e/0x120 > [42949380.750000] 67efbd28: [<60017a30>] do_signal+0x20/0x30 > [42949380.750000] 67efbd38: [<60016795>] interrupt_end+0x45/0x60 > [42949380.750000] 67efbd58: [<6002be8c>] userspace+0x15c/0x2f0 > [42949380.750000] 67efbd78: [<6001b502>] copy_to_user_skas+0x72/0x90 > [42949380.750000] 67efbde8: [<6001a8fe>] fork_handler+0xee/0x100 > [42949380.750000] > [42949380.750000] * route del -host 192.168.0.2 dev tap0 > [42949380.750000] * bash -c echo 0 > /proc/sys/net/ipv4/conf/tap0/proxy_arp -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
