Does the caps lock LED blink when the machine is locked up?  Can you
get a log when this happens using netconsole[1] or a serial
console[2]?

I'd also be interested to hear whether the 3.5.y kernel from
experimental reproduces the same bug.  If it does, we can try to get
help from upstream, and if it doesn't, we can try to find what patch
fixed it and apply the same to wheezy.

Thanks for a clear report, and hope that helps.

Sincerely,
Jonathan
