Hi,
I got the following oops when mcopy'ing to a floppy drive with no disk in it. I won't be able to read my mail until Sunday, so if you need further info it'll have to wait until then.
Regards, -Udo.
ksymoops 2.4.4 on i686 2.5.19. Options used -V (default) -K (specified) -l /proc/modules (default) -o /lib/modules/2.5.19/ (default) -m /boot/System.map-2.5.19 (specified)
No modules in ksyms, skipping objects No ksyms, skipping lsmod Unable to handle kernel NULL pointer dereference at virtual address 00000098 c01d40da *pde = 00000000 Oops: 0002 CPU: 0 EIP: 0010:[<c01d40da>] Not tainted Using defaults from ksymoops -t elf32-i386 -a i386 EFLAGS: 00010046 eax: 00000000 ebx: 00000286 ecx: 00000001 edx: 00000000 esi: e6317e78 edi: c155ec08 ebp: efcd1640 esp: e6317e34 ds: 0018 es: 0018 ss: 0018 Stack: e6317e5c c01de3c3 00000000 efcd1640 00000000 e6317e78 efcd1640 00000200 00000001 c0300200 00000001 00000000 e6317e64 e6317e64 c155ec08 00000400 00000000 00000000 00000000 efcd1640 00000000 00000000 00000001 00000000 Call Trace: [<c01de3c3>] [<c01de300>] [<c01de44a>] [<c01de5a0>] [<c0134ffb>] [<c01de1b6>] [<c013517c>] [<c0135382>] [<c012f191>] [<c012f0a2>] [<c012f447>] [<c0106b47>] Code: 0f b3 82 98 00 00 00 19 c0 85 c0 74 19 8b 82 98 00 00 00 a8
