Hello I've experienced this kernel panic on sys-kernel/gentoo-sources-2.6.31-r6. This has happened for the first time on a new system I've built, so not sure if it is reproducible. Here're the lines from /var/log/messages...

When the crash happened, I wasn't at the computer, but the mythbackend was recording two programs at the same time, with different tuners. If details about the mythbackend, tuners, etc. are needed, I can add those too. Please let me know if there is any thing else I can furnish.
