The lockup happened again last night. kernel: [38460.336022] BUG: soft lockup - CPU#3 stuck for 22s! [umount:24238]. This time there was more information in the syslog than there has been in the past, including a couple call traces and stack traces. The relevant portion of the syslog is attached. I'll try installing the upstream kernel next.
