Comment 20 for bug 60053

I can comfirm this also. This happens for me after the machine has been up for 10 or so minutes and I loose ndiswrapper functionality (the wireless card wont respond).

Turning off Hyperthreading functionality allows the machine to keep running without issue.

When this occurs I get the following trace in the kernel log
