Hello list,
I get the oops below on my Thinkpad after leaving it on for a day or two. I
haven't found a way to trigger it yet: after the OOPS the machine still
works, but it usually locks up during shutdown. The kernel is not tainted and
the only non-vanilla driver I'm using is the ipw2100 for the wireless
card .I've tested the RAM with memtest86+ and everything seems to be ok. This
has happened since at least 2.6.15.
Please CC: me on all replies, I'm not subscribed to the list.
Let me know if you need any other info and what I can do to track down the
problem. Kernel config is compressed and attached.
Thanks for your attention,
Silla Rizzoli
