Comment 1 Dave Jones 2012-03-05 22:20:26 UTC 
The address it's faulted on is RDI: 00ff880005275660

That address has lost it's upper 8 bits. Looks like something scribbled 0x00 over random memory.

Was this after a suspend or hibernate ?
Comment 2 Mark Knoop 2012-03-06 11:02:27 UTC 
No. This hasn't happened on newer kernels, I think since 3.0.
Comment 3 Dave Jones 2012-03-06 15:27:07 UTC 
ok, let's close it out. If it reoccurs, feel free to reopen.

thanks.
