I was running an ircd process today, when the process itself cored, and
the kernel had an oops while creating the core file. I'm running kernel
2.2.1 with no patches on an intel p166, 32 meg of ram, egcs-2.92.16
19981019 (gcc2 ss-980609 experimental), and libc 5.4.46.

The oops is as follows:
Unable to handle kernel paging request at virtual address c7be820c
current->tss.cr3 = 01274000, %cr3 = 01274000
*pde = 00000000
Oops: 0000
CPU: 0
EIP: 0010:[<c012f929>]
EFLAGS: 00010246
eax: 00000000 ebx: c0749ec8 ecx: ffffffff edx: 00000000
esi: c7be820c edi: c0749ca4 ebp: c0748000 esp: c0749c3c

The result of ksymoops was:
>>EIP: c012f929 <writenote+15/b0>

When using the command "strings core > corefile", it returned a file
containing nothing but "CORE". I was able to reproduce this everytime I
segfaulted the process.

I am not on this mailing list, so please cc any replies to me. Thanks.
