BUG: soft lockup detected on CPU#0!

| | Comments (0)
Update:  all customers should be back.   The RAID was broken by the unclean restart, so expect degraded I/O while it finishes rebuilding.  

Update:  I fixed the grub boot records.   The box is back up,   the virtuals will be coming on line one at a time.   

Update: knife isn't rebooting remotely.  (I mean, the pdus cycle power, but knife hangs up somewhere betwen post and boot)  I'm heading down to the co-lo to jerk with it in person.


not a good morning.  I'm rebooting knife right now.
