Hi, My dual Xeon P4 (with HT, 1 GB RAM) has just oopsed on shutdown, due to a lockup in the CFQ scheduler (I think). The compiler was gcc-3.4.3.
NMI Watchdog detected LOCKUP on CPU2, eip c026d86d, registers: Modules linked in: snd_pcm_oss snd_mixer_oss snd_usb_audio snd_usb_lib snd_intel8x0 snd_seq_oss snd_seq_midi snd_emu10k1_synth snd_emu10k1 snd_ac97_codec snd_pcm snd_page_alloc snd_emux_synth snd_seq_virmidi snd_rawmidi snd_seq_midi_event snd_seq_midi_emul snd_hwdep snd_util_mem snd_seq snd_seq_device snd_rtctimer snd_timer snd nls_iso8859_1 nls_cp437 vfat fat usb_storage sg sbp2 radeon i2c_algo_bit emu10k1_gp gameport deflate zlib_deflate zlib_inflate twofish serpent aes_i586 blowfish des sha256 crypto_null af_key binfmt_misc eeprom i2c_sensor button processor psmouse pcspkr p4_clockmod speedstep_lib usbserial lp nfsd exportfs md5 ipv6 sd_mod scsi_mod autofs nfs lockd sunrpc af_packet ohci_hcd parport_pc parport e1000 video1394 raw1394 i2c_i801 i2c_core ohci1394 ieee1394 ehci_hcd soundcore pwc videodev uhci_hcd usbcore intel_agp agpgart ide_cd cdrom ext3 jbd CPU: 2 EIP: 0060:[<c026d86d>] Not tainted VLI EFLAGS: 00200086 (2.6.10) EIP is at _spin_lock+0x7/0xf eax: f76af01c ebx: f6f88ba0 ecx: f6f88bac edx: f6f8881c esi: f42a7dc0 edi: f6f88810 ebp: f6f8881c esp: f64dff6c ds: 007b es: 007b ss: 0068 Process nautilus (pid: 6111, threadinfo=f64df000 task=f7b28520) Stack: c01f07ac 00200286 f7495af4 f6deb780 00000000 f7b28520 f64df000 c01ece22 f64df000 c011d6c9 7fffffff 00000001 00000000 b6640a40 00000000 00000000 00000000 00000000 00000000 f64df000 c011d76a c0102dc3 00000000 b6640bf0 Call Trace: [<c01f07ac>] cfq_exit_io_context+0x54/0xb3 [<c01ece22>] exit_io_context+0x45/0x51 [<c011d6c9>] do_exit+0x381/0x402 [<c011d76a>] next_thread+0x0/0x4b [<c0102dc3>] syscall_call+0x7/0xb Code: 9f c0 c3 89 c2 f0 81 28 00 00 00 01 0f 94 c0 84 c0 b9 01 00 00 00 75 09 f0 81 02 00 00 00 01 30 c9 89 c8 c3 f0 fe 08 79 09 f3 90 <80> 38 00 7e f9 eb f2 c3 f0 81 28 00 00 00 01 74 05 e8 35 ea ff console shuts up ... ___________________________________________________________ ALL-NEW Yahoo!
