I get occasional full-system freezes triggered by Firefox :
- keyboard unresponsive
- cannot switch to vt
- can't ssh (still pings though)
From the logs, it seems at least part of the system is still alive as we can see kwin messages, lid open/close events (no suspend though) and smc event (when forcing shutdown).
