I agree on the random video RAM contents thing - that would have been my first guess.
The wireless connection Matt and I both had trouble with, with ath(4), was using WPA2, though I don't know the device. If you want to try different setups and see what works and what doesn't, that would make a useful report. Maybe set sysctl kern.emergency_intr_enable=1? I don't remember if that's already been suggested, or if that would apply in this case. On Mon, May 9, 2011 at 4:49 AM, Matthias Rampke <[email protected]> wrote: > > On Montag, 9.
