Two oops here, first is floppy mount on 2.3.38 (i586),
second is floppy umount on 2.3.37 (i486). Last known
no problem version was 2.3.36 (i586). Rarely use the
floppy.

ksymoops 0.7c on i586 2.3.38. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.3.38/ (default) -m /usr/src/linux/System.map (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.

No modules in ksyms, skipping objects Unable to handle kernel NULL pointer dereference at virtual address 00000008 c01b0fa3 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[floppy_release+35/160] EFLAGS: 00010246 eax: c69b0000 ebx: 00000000 ecx: 00000000 edx: c69b0000 esi: c12c4160 edi: fffffff4 ebp: 00000200 esp: c6595f30 ds: 0018 es: 0018 ss: 0018 Process mount (pid: 349, stackpage=c6595000) Stack: fffffff4 c013363f c69b92c0 00000000 c65fd2c0 c69b9900 c69962a0 c69a41e0 c01336b2 c12c4160 00000000 c012d10f c69b9900 c65fd2c0 c65fd2c0 c69962a0 00000000 c012d151 c65fd2c0 c65fd2c0 c65fd2c0 c012c10b c65fd2c0 c6594000 Call Trace: [blkdev_put+143/240] [blkdev_close+18/32] [__fput+31/80] [_fput+17/64] [filp_close+107/128] [do_close+91/112] [sys_close+12/16] Code: 8b 41 08 50 51 e8 13 1e f8 ff be 08 58 29 c0 8d 04 5b 8d 04 Using defaults from ksymoops -t elf32-i386 -a i386
