>Description:
After a few hours of uptime or during intensive disk i/o
(like make world, bonnie, iozone etc.), the system suddenly stops to
access the harddisks. After a few more moments, everthing hangs.
Then it reboots.
This doesn't occur with a about 2 weeks old kernel binary (i don't have
the sources of this one anymore ...).
>How-To-Repeat:
Wait for a few hours or do heavy disk i/o.
