I have experienced similar, if not the same behavior with both 1.6 and
-current. That kind of lock-up has only happened to me when there's
either a disk-related problem or overheated processor, but I've never
used the multiprocessor kernel.
One time, I just had the RAID partitions misaligned on the disk(s): It
ran fine for a few weeks, but got worse as time went on and more of the
drive was being used. Then after a few weeks of putting-up with the
intermittent lock-ups it got to the point where the parity re-write
locked it up. Needless to say, a new disklabel fixed her right up.
Another time it was a bad IDE controller...It never hurts to keep a few
around for testing. And yet another time it was a dying HDD.
So, if you haven't already:
- check your disklabels. even the slightest mistake could lead to this
- check your dmesg for any nasty looking I/O messages during disk and
- eliminate one hardware component at a time.
Maybe that'll help you determine whether you need to update the kernel
or not. Then again, it might be easier to upgrade/downgrade before
checking all that other stuff... s'up to you.
