Complete system freeze when using atheroswifi with an SMP system.
|Reported by:||jstressman||Owned by:||colin|

I was getting a number of complete system locks while trying to install the BeZillaBrowser package, or just in general after a variable amount of time (sometimes immediately when reaching the desktop, or maybe after 10 minutes etc).
So I began testing and removed the atheroswifi driver. This "fixed the problem" and I ran the computer for about an hour with no problems. So then I restored the driver and did some research into whether or not anyone had had any problems with the BSD drivers themselves, where I found that this seemed to be a known LOR (lock order reversal) problem and the email recommended to disable SMP as a workaround until the problem was fixed.
So I disabled SMP and was able to surf the net, chat, etc... for 17 hours with no problems before I rebooted the system myself.
I re-enabled SMP for testing a bit ago and was able to freeze the system completely within less than 2 minutes of using the internet.
This is a hard freeze where the system instantly becomes completely unresponsive. No keyboard shortcuts work etc. (No alt+sysreq+d for KDL, no ctrl+alt+del etc) You have to press the power button on the computer itself to shut off the machine.
Here are some of the other links I was looking at that may be related:
I'm also attaching the output of listdev, and a few copies of the syslog from before the crash.
