Description of problem:
Using Alt-SysRq-t to list the tasks causes a kernel oops. Unfortunately, the
oops never makes it into /var/log/messages, so I can't run ksymoops on it.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. echo "1" > /proc/sys/kernel/sysrq
Actual Results: Kernel oops
Expected Results: Task listing
Yup this happened here too. After some debugging I've now fixed it; will appear
in rawhide as kernel 2.4.18-0.16. Thanks for the report!
