[OOPS] oops with linux-2.5.64 + cset-1.1068.1.17-to-1.1166.gz

[Craig Schlenter]

Hi

Anyone interested in a kernel BUG at include/linux/dcache.h:266?

Oops and dmesg is shown below. I can supply more info if needed
but mail responses will be sluggish as I can only check this
email account once per day, sorry.

I think it happened when I control-C'ed wvdial to drop the
ppp connection. 2.5.63 was fine IIRC but it hadn't been used
much on the box (which functions as a dialup firewall on
ancient hardware).

Thank you!
