Hi!

Is this the new 4312 (BCM94312HMGB AKA 575920-001), with integrated
Bluetooth? I haven't seen this issue on my machines with a regular
4312, so it is probably related to the DMA error, or maybe it is
specific to the new 4312. If you can, please check whether the actual
model number printed on the card is the new one.

Thanks,
G?bor
