After reverting yesterday's glibc packages, I noticed my system freezing after several hours of "mostly idle" (actually, only azureus active).

After the last one, I noticed the following in /var/log/messages:

Oct 28 19:17:22 localhost kernel: Uhhuh. NMI received. Dazed and confused, but trying to continue Oct 28 19:17:22 localhost kernel: You probably have a hardware problem with your RAM chips

I ran memtest86+ for about 14 hours, but detected nothing.

This is running on 4 week old Thinkpad X60.

Any thoughts?
