So right after sending my last mail, I rebooted, and restarted the run on the same kernel again. As I was writing this mail, this happened. [ 524.420897] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [trinity-c178:20182] and that's all that made it over the console. I couldn't log in via ssh, and thought "ah-ha, so it IS bad". I walked over to reboot it, and found I could actually log in on the console. check out this dmesg..
