This doesn't look related to the other 2.6.39.4 threads (that seem to be all solely build-related). I get this during boot on a 64-bit Debian Squeeze. 2.6.39.3 boots just fine. it's slightly garbled at the beginning, but I figured the context was important enough to leave it untouched. If there's anything helpful I should send along, I'll do so immediately. If it'd also be helpful, I can use 2.6.39.3's version of check_kill_permission in 2.6.39.4, if you don't think it'd cause additional issues. Thanks!

[ 19.225066] Fixing recursive fault but reboot is needed!

This should be fixed in the latest patch I just uploaded. Please let me know if you still have any issues.

Thanks for the report,
-Brad

Will do. As always, you guys are awesome.

Sorry, should''ve posted an update but yesterday was insane. The new patch works just fine for me. Thanks again!
