Comment 23 for bug 359231

Hi BUGabundo,

Unfortunately the last set of attachments didn't seem to capture any kernel panic/oops. So I'm pasting a stack trace from one of your original kern.log files. The next time you experience a lock up, could you try to ssh into the machine if possible and see if anything is captured in your dmesg? It might not also hurt to give the most recet 2.6.29 kernel a test to see if this exists with the upstream kernel as well - https://wiki.ubuntu.com/KernelMainlineBuilds.
