Re: DMA issues with the SKGE drivers

Yes, I guess I'd be able to, but only after testing it.
I'm currently waiting a new cooler that would support the 110 W TDP of 
my Opteron 180 X2.
The previous cooler I tested were definitely not good enough for cooling 
that CPU.
Just running MemTest86+ for too long made the CPU overheat.
Even the Arctic Cooler Freezer 7 CO wasn't good enough.
