Re: [cooker-amd64] Dual Opteron hangs in openoffice

[Martin Johnson]

Hi,

I tried bios 1.07 (the oldest) and 2.02 (the latest), neither had the fix.
I don't think I should post the fix here since it needs a secret password 
to access that block of MSRs, but if anybody needs it, just email me 
directly.

This problem only affects older Opterons (b3) not the latest revision (c0)
but the 240s and 242s being sold now are likely to still be b3.
