Hi,
Since a couple of kernel updates ago, this machine hasn't been too solid.
I've experienced solid lock-ups, where only powering off will allow me to
restart the machine.
Tonight it happened again, and I tried to do an <alt> <sys req> S
to sync the disk (and preserver my file system!) and got the following. I
think I may have had this before, but with X running at the time the machine
freezes, couldn't see it. Tonight I was in the console when it happened, so
I was able to see the messages.
SysRq: Emergency Sync
Syncing device 03:05 .. scheduling interupt

in interupt handler - not syncing
(sorry, snipped out the registers some of the detail. If it will help let me
know and I'll write it all down.)
