[Bug 656039] Re: Total freeze of the system (general protection fault)

[Alessio Bolognino]

This happens once a day, it's super annoying and it's definitely a regression from Lucid.
I had it happen while casual browsing, or editing stuff or whatever.
Sometimes I'm able to ssh from another machine and use the sysrq magic keys echoing characters to /proc/sysrq-trigger, but I rarely get the machine to do a clean reboot. Sadly, no, sysrq key on my keyboard (macbook).
