The last time I checked, AMD did not have a BKDG ("bios and kernel
developer's guide") for family 15h yet, so I don't know about the
details of C1E on Bulldozers. Of course this is entirely NetBSD's fault,
as all C1E-problems are caused by the fact that C-states are not generally
supported, whatever their name may be.

Could be, but no idea.

Yes.

Re: AMD FX-6100 boot pauses with ACPI

It would be best to get the output of 'cpuctl identify 0' from the 
system in question.  AMD cpu families include the extended family field, 
and it could be that Bulldozer is family 16 or 17...

Bulldozer is family 0x15.
