New oops in 2.4.18 kernel paging [was Re: Oops report in filemap_fdatawait]

  Hi.

Yesterday I sent in an oops and today I have 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.
