I've got a very similar setup, but i've got a SCSI hard drive as well.
In copying a rather large file (600+ MB) from my home directory (on the
SCSI drive) to my IDE drive (on the promise controller, ata/100). scsi
drive is ext2, the ide drive is vfat (basically to share movies and
music w/ windoze). First try at copying, I got corruption. Second try,
cp segfaulted. Looked, and sure enough, had an oops sitting for me in
syslog, so here it is:

ksymoops 2.3.7 on i686 2.4.1-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.1-ac2/ (default)
-m /boot/System.map-2.4.1-ac2 (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.
