It only happens when running Azareus with IBM's Java (our's isn't ready yet). So far I was able to reproduce the problem on all -mm versions within one hour. Otherwise the kernels seem to work fine -- no lockup unless I run Azareus. I'm running rc2-mm3 without the timer- patches now. It's up for 6 days now and survived downloading all Ubuntu torrents over ten times. > Is it possible to perform any additional debugging? > Do you think there's anything unusual in your driver lineup or in > your workload which would cause you to be the only person who is > observing this? I'm might be the only one using evdev on ppc64. And I don't know how popular LVM2 is on disks with Macintosh labels. I had to set it up manually when I installed the machine, Debian's installer couldn't handle it at that time. Workload is normal, the lockups happen with just X and Azaereus. (The machine also runs mysqld, apache, and a few other daemons. But I don't have to put load on these to make the machine lock up.)
