Same issue here, entirely different sounding hardware. Running
NetworkManager. Your symptoms are identical to mine. I have not found
any pattern here, although increased network usage sounds like a good
guess. Running a system monitor applet on my panel set to measure system
load average, and have observed on a few occasions the load jumping off
the chart (13 or so!) before the system entirely freezes. Usually
freezes about a second after the load spikes upwards. Unfortunately, I
have not been able to confirm this consistently since the crash is so
inconsistent itself.
Alt+SysRQ+1 then Alt+SysRQ+t do nothing. Mind you, my log is being
spammed with an error message about wireless encryption (thanks,
Netgear!), but I am fairly certain it achieved nothing. (Feel free to
show otherwise).
