So, I plugged in e680 motorola phone, played a bit with minicom on /dev/ttyACM0, and when I closed minicom, got this oops. USB is useless, got to reboot computer to use it again! it's vanilla 2.6.11.7 oops attached.
ksymoops 2.4.9 on i686 2.6.11.7. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.6.11.7/ (default) -m /boot/System.map-2.6.11.7 (default) Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options. Error (regular_file): read_ksyms stat /proc/ksyms failed No modules in ksyms, skipping objects No ksyms, skipping lsmod Oops: 0000 [#1] CPU: 0 EIP: 0060:[<c01efc59>] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010246 (2.6.11.7) eax: 00000000 ebx: 00000000 ecx: ffffffff edx: c17d3df8 esi: 00000001 edi: 00000000 ebp: c74a9d70 esp: c74a9d64 ds: 007b es: 007b ss: 0068 Stack: c03a38e0 c17d3dd4 d269e378 c74a9d94 c01efcda c17d3df8 c041e888 d4b03d2c 00000001 c03a38e0 c17d3dd4 d269e378 c74a9dd8 c025f75c c17d3df8 000000d0 d269e360 d5efc829 c74a9dc4 c01f3818 d5efc829 2a1037d7 00000000 d3481e6c Call Trace: [<c010340f>] show_stack+0x7f/0xa0 [<c01035a6>] show_registers+0x156/0x1d0 [<c01037a8>] die+0xc8/0x150 [<c0114d62>] do_page_fault+0x462/0x699 [<c01030a7>] error_code+0x2b/0x30 [<c01efcda>] kobject_get_path+0x1a/0x70 [<c025f75c>] class_hotplug+0x6c/0x1b0 [<c01f09bb>] kobject_hotplug+0x1cb/0x2b0 [<c01f009b>] kobject_del+0x1b/0x30 [<c025fc14>] class_device_del+0xa4/0xc0 [<c025fc42>] class_device_unregister+0x12/0x20 [<e0fcf529>] acm_tty_close+0xc9/0x110 [cdc_acm] [<c024921d>] release_dev+0x6ad/0x7f0 [<c0249801>] tty_release+0x11/0x20 [<c0154a9c>] __fput+0xec/0x120 [<c01531d0>] filp_close+0x50/0x90 [<c015325c>] sys_close+0x4c/0x70 [<c0102e93>] syscall_call+0x7/0xb Code: e6 89 34 24 e8 99 11 fa ff eb dc 8d b4 26 00 00 00 00 55 89 e5 8b 55 08 57 56 be 01 00 00 00 53 31 db 8b 3a b9 ff ff ff ff 89 d8 <f2> ae f7 d1 49 8b 52 24 8d 74 31 01 85 d2 75 e7 5b 89 f0 5e 5f >>EIP; c01efc59 <get_kobj_path_length+19/30> <===== >>ecx; ffffffff <__kernel_rt_sigreturn+1bbf/????> >>edx; c17d3df8 <pg0+13a0df8/3fbcb400> >>ebp; c74a9d70 <pg0+7076d70/3fbcb400> >>esp; c74a9d64 <pg0+7076d64/3fbcb400> Trace; c010340f <show_stack+7f/a0> Trace; c01035a6 <show_registers+156/1d0> Trace; c01037a8 <die+c8/150> Trace; c0114d62 <do_page_fault+462/699> Trace; c01030a7 <error_code+2b/30> Trace; c01efcda <kobject_get_path+1a/70> Trace; c025f75c <class_hotplug+6c/1b0> Trace; c01f09bb <kobject_hotplug+1cb/2b0> Trace; c01f009b <kobject_del+1b/30> Trace; c025fc14 <class_device_del+a4/c0> Trace; c025fc42 <class_device_unregister+12/20> Trace; e0fcf529 <pg0+20b9c529/3fbcb400> Trace; c024921d <release_dev+6ad/7f0> Trace; c0249801 <tty_release+11/20> Trace; c0154a9c <__fput+ec/120> Trace; c01531d0 <filp_close+50/90> Trace; c015325c <sys_close+4c/70> Trace; c0102e93 <syscall_call+7/b> This architecture has variable length instructions, decoding before eip is unreliable, take these instructions with a pinch of salt.
