soft lockup - CPU#0 stuck for 61s! [kswapd0:267]
From: Scott Phelps
Date: Tue Feb 03 2009 - 10:37:55 EST
I was seeing this error after four to five days running kernel
2.6.27-9-generic from a default Intrepid install. I subsequently
installed the latest stable release, 2.6.28.3, and now just saw the
error after twenty days up uptime.
The hardware is a Sun x4500
Here's a dump from syslog:
