Just a laptop with 16G of RAM, no clear reproducer -  Chrome with a lot of
tabs, a mail reader, a bunch of SSH windows, and the next thing I know, it's
locked up good and solid with wreckage in /sys/fs/pstore :)

I got bit a third time a little while ago.  Will test the patches and see if
they help - looks like I'm averaging two hours or so of active use before it
hits, so it shouldn't take long before I know if the issue is swatted...
