Hi,
With an update to v2.9.1.845.gc7506-DEVELOPMENT these panics have
become quite frequent (several times a day).
I finally got a dump out of one of the crashes - it's packed up at
http://www.sohara.org/crash.tgz
For the time being I'm running the box with a UP kernel in the hope
that it will be stable.
