I started doing multiple mencoder/ffmpeg commands, and as I ran one more, the system froze up (as in everything froze, even running ssh sessions not doing any IO)

sysrq-W output:

I'm assuming btrfs is to blame, but I'm not certain. Hopefully someone knowledgeable can have a look.

Thanks,
Marc

Same exact bug/hang happened again, same condition. Started one ffmpeg too many, and everything stopped.
