Hello -
I have been running the 2.4.15-pre kernels and
have found an interesting oops. I can reproduce
it immediately, and reliably, just by issuing an ssh
command (as a normal user).
Hardware: Pentium III 933 w/512 MB RAM
Red Hat 7.1+ updates
I have 2 eepro 100 cards and am running
an iptables firewall.
The condition exists in 2.4.15-pre1 and -pre2.
I have not seen this before (2.4.14 is fine)
Tonight I compiled 2.4.15-pre2 and ran dbench
for awhile, with good results.
Then I tried the simple "ssh <somehost>"cmd
that locked up -pre1 - sure enough, it locked
up the system again -
Here is the hand-copied, decoded oops:
ksymoops 2.4.3 on i686 2.4.15-pre2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.15-pre2/ (default)
-m /boot/System.map (specified)
