Subject: Oops: 2.4.15-pre6 in write_intr (ide related?)

I just got this oops on a PPro200 with 32mb ram running 2.4.15-pre6. I was
doing some memory stress testing (using perl).

Decoded and raw oops follows:

logger:~# ksymoops -m /usr/src/linux/System.map < oooops
ksymoops 2.4.3 on i686 2.4.15-pre6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.15-pre6/ (default)
     -m /usr/src/linux/System.map (specified)

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod
file?
