Hello, after running a few instances of bittorent-curses on 2.6.22 - 2.6.22.3 it takes about 15min to 2hrs for my System to hang. 2.6.21.7 is definately fine, 2.6.21 probably (ran for 4hrs without hanging). If I'm lucky the Oops below makes it to my syslog (unfortunately SysRq-{p,s,i} doesn't work when it hangs, neither can I ssh into it): Aug 18 19:47:41 draco kernel: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 Aug 18 19:47:41 draco kernel: printing eip: Aug 18 19:47:41 draco kernel: c038fcba Aug 18 19:47:41 draco kernel: *pdpt = 0000000033830001 Aug 18 19:47:41 draco kernel: *pde = 0000000000000000 Aug 18 19:47:41 draco kernel: Oops: 0002 [#1] Aug 18 19:47:41 draco kernel: SMP Aug 18 19:47:41 draco kernel: Modules linked in: snd_hda_intel snd_emu10k1 cls_u32 sch_sfq sch_htb snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_pcm_oss snd_mixer_oss rfcomm hidp l2cap nfsd exportfs lockd sunrpc coretemp hwmon eeprom snd_rawmidi snd_ac97_codec hci_usb ac97_bus snd_seq_device snd_util_mem snd_pcm bluetooth snd_hwdep snd_timer snd snd_page_alloc i2c_i801 emu10k1_gp gameport i2c_core sg Aug 18 19:47:41 draco kernel: CPU: 0 Aug 18 19:47:41 draco kernel: EIP: 0060:[<c038fcba>] Not tainted VLI Aug 18 19:47:41 draco kernel: EFLAGS: 00210202 (2.6.22.2poison #14) Aug 18 19:47:41 draco kernel: EIP is at tcp_sendmsg+0x40a/0xb70 Aug 18 19:47:41 draco kernel: eax: 00000000 ebx: ec5b807c ecx: c04b43a0 edx: ec5b807c Aug 18 19:47:41 draco kernel: esi: ec5b8000 edi: 00000100 ebp: ec524180 esp: f3a11d30 Aug 18 19:47:41 draco kernel: ds: 007b es: 007b fs: 00d8 gs: 0033 ss: 0068 Aug 18 19:47:41 draco kernel: Process bittorrent-curs (pid: 3974, ti=f3a10000 task=f3a0e000 task.ti=f3a10000) Aug 18 19:47:41 draco kernel: Stack: ffffffff ebe562f5 0000000b 00000000 f3a11d94 00000000 ec5b807c 00000000 Aug 18 19:47:41 draco kernel: 00000001 00100100 f3a11f40 00000000 00000040 00000200 00000200 000004b6 Aug 18 19:47:41 draco kernel: 08604707 00200200 f3e5c798 eeaa4b40 00000000 f3a0e000 000001f5 00100100 Aug 18 19:47:41 draco kernel: Call Trace: Aug 18 19:47:41 draco kernel: [<c03ac267>] inet_sendmsg+0x37/0x70 Aug 18 19:47:41 draco kernel: [<c03511ef>] sock_sendmsg+0xbf/0xf0 Aug 18 19:47:41 draco kernel: [<c012fe60>] autoremove_wake_function+0x0/0x50 Aug 18 19:47:41 draco kernel: [<c01188f0>] default_wake_function+0x0/0x10 Aug 18 19:47:41 draco last message repeated 3 times Aug 18 19:47:41 draco kernel: [<c015589d>] find_extend_vma+0x1d/0x70 Aug 18 19:47:41 draco kernel: [<c03515cf>] sys_sendto+0x12f/0x180 Aug 18 19:47:41 draco kernel: [<c0139dfc>] futex_wake+0xac/0xd0 Aug 18 19:47:41 draco kernel: [<c013a4dd>] do_futex+0x6bd/0xbd0 Aug 18 19:47:41 draco kernel: [<c0351653>] sys_send+0x33/0x40 Aug 18 19:47:41 draco kernel: [<c03525c2>] sys_socketcall+0x142/0x280 Aug 18 19:47:41 draco kernel: [<c0205d20>] copy_to_user+0x30/0x60 Aug 18 19:47:41 draco kernel: [<c0102a92>] syscall_call+0x7/0xb Aug 18 19:47:41 draco kernel: ======================= Aug 18 19:47:41 draco kernel: Code: 85 fb 06 00 00 80 ca 10 8b 83 94 00 00 00 88 53 68 f0 81 00 00 00 01 00 8b 44 24 18 ff 40 08 8b 54 24 18 8b 42 04 89 13 89 43 04 <89> 18 89 5a 04 8b 8e 2c 01 00 00 85 c9 0f 84 19 06 00 00 8b 83 Aug 18 19:47:41 draco kernel: EIP: [<c038fcba>] tcp_sendmsg+0x40a/0xb70 SS:ESP 0068:f3a11d30 Aug 18 19:47:51 draco kernel: Aug 18 19:47:51 draco kernel: Pid: 3812, comm: X Aug 18 19:47:51 draco kernel: EIP: 0060:[<c014a4c2>] CPU: 0 Aug 18 19:47:51 draco kernel: EIP is at __get_free_pages+0x22/0x40 Aug 18 19:47:51 draco kernel: EFLAGS: 00003246 Not tainted (2.6.22.2poison #14) Aug 18 19:47:51 draco kernel: EAX: 000000d0 EBX: 000000d0 ECX: c0496b40 EDX: 00000000 Aug 18 19:47:51 draco kernel: ESI: 00000000 EDI: f5ba1be4 EBP: f49a4d80 DS: 007b ES: 007b FS: 00d8 Aug 18 19:47:51 draco kernel: CR0: 8005003b CR2: b7384000 CR3: 37165000 CR4: 000006f0 Aug 18 19:47:51 draco kernel: [<c01734b6>] __pollwait+0xa6/0x100 Aug 18 19:47:51 draco kernel: [<c03c9597>] unix_poll+0x17/0xa0 Aug 18 19:47:51 draco kernel: [<c03500bc>] sock_poll+0xc/0x10 Aug 18 19:47:51 draco kernel: [<c0172bec>] do_select+0x25c/0x490 Aug 18 19:47:51 draco kernel: [<c0173410>] __pollwait+0x0/0x100 Aug 18 19:47:51 draco kernel: [<c01188f0>] default_wake_function+0x0/0x10 Aug 18 19:47:51 draco last message repeated 19 times Aug 18 19:47:51 draco kernel: [<c0172fe8>] core_sys_select+0x1c8/0x2f0 Aug 18 19:47:51 draco kernel: [<c0166a30>] do_readv_writev+0x120/0x190 Aug 18 19:47:51 draco kernel: [<c03503c0>] sock_aio_write+0x0/0x110 Aug 18 19:47:51 draco kernel: [<c017355d>] sys_select+0x4d/0x1b0 Aug 18 19:47:51 draco kernel: [<c0166adc>] vfs_writev+0x3c/0x50 Aug 18 19:47:51 draco kernel: [<c0166f97>] sys_writev+0x47/0x80 Aug 18 19:47:51 draco kernel: [<c0102a92>] syscall_call+0x7/0xb Aug 18 19:47:51 draco kernel: ======================= --- It's also attached together with one from a tainted 2.6.22.3 The error is reproducable for me by running 4 bittorent instances and wating. 2.6.22 lives no longer than 2hrs, so when bisecting I assumed it was good after 4hrs ... so I may as well have taken a wrong turn.
