Hello,
I just saw somebody on slashdot mention this:
"
From the errata:
Executing CPUID with EAX = 7 and ECX = 0 may return EBX with bits [3] and
[8] set, incorrectly indicating the presence of BMI1 and BMI2 instruction
set extensions.
Attempting to use instructions from the BMI1 or BMI2 instruction set
extensions will result in a #UD exception.
"

This seems very bad to me.
Without BMI Skylake would not be worth it to me ! ;) =D
Must have BMI support.
I may have to skip Skylake or wait for steppings to fix it, but it says: NO
FIX !?
Wow... strange...
Good idea to check errate before deciding on what processor to get from now
on ! ;) =D
Bye,
Skybuck =D

Would have been nice if your parents had waited for stepping instead
of failing to flush you.

Jesus, so many bugs! First time I read an Intel CPU errata, are their
