The system freezes randomly and no longer accepts any input and after a =
minute of being 'frozen' reboots.
Initiaily thought it was related to firefox as this can usualyl crash it =
'randomly' , Seems to be an issue with the now un-supported ural0 =
driver.
I'm fairly new to kernel debugging so am not sure what details people =
need, hope this helps.
Any questions/requests for more info are no problem.
