Subject: Machine Check Exception

Hi,

while bugging the wireless devs about a freeze i've discovered an hardware 
bug:

HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 0 4 northbridge   Northbridge Watchdog error
       bit57 = processor context corrupt
       bit61 = error uncorrected
  bus error 'generic participation, request timed out
      generic error mem transaction
      generic access, level generic'
STATUS b200000000070f0f MCGSTATUS 4

this is triggered byt the ath9k wireless driver when booting with smp > 1
here is the kernel bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=11527#c68

here I asked support in the official AMD forum:
http://forums.amd.com/forum/messageview.cfm?catid=22&threadid=101051


I ask you this as you are the "CPU ERRATA WORKAROUNDS" man,
and I CC people which are listed in the "X86 ARCHITECTURE (32-BIT AND 64-BIT)"
entry.

Best Regards,
Matteo Croce
