Hi.
[I apologize if this was sent more than once.]
Two days ago I sent in an oops and yesterday I had 2 others which forced me
to hard reboot.
Kernel: 2.4.18
Hardware: Pentium III, 500 MHz PC
Symptom: After the first oops yesterday, everything seemed fine.
Then after these 2 oops, the load started going way up, I couldn't umount
anything, and I couldn't shutdown gracefully. All 3 oops were run through
ksymoops and attached below.
The messages for each oops were:
May 27 04:07:35 manic kernel: Unable to handle kernel paging request at virtual address 032f039b
May 28 15:55:27 manic kernel: Unable to handle kernel paging request at virtual address 00048c22
May 28 16:29:06 manic kernel: <1>Unable to handle kernel paging request at virtual address 00048c22
The ksymoops outputs are attached for each. The first oops occured in
fdatawait, then in ppp, and finally in umount.
I did not see this problem prior to 2.4.18.
Please let me know what, if anything, I can do to help you fix this.
See excerpts of yesterday's message below for additional system info.
Thank you.

Kernel version: 2.4.18 (no custom mods or patches)
I do not know what triggers the problem as it is rather sporadic.
My environment is: PIII 500 MHz CPU on standard PC hardware
with 642MB RAM, ASUS P3B motherboard, 1 IDE drive,
2 SCSI drives, 2 ethernet boards, a soundcard, ReiserFS, etc.

ksymoops 2.4.4 on i686 2.4.18. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.18/ (default)
-m /boot/System.map-2.4.18 (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.
