Was this patch committed? I don't recall seeing an svn notice.

When it occurs, it is a fatal DMA error, and this streams on the console
until reboot. In order to get the card to work again (with either bwn
or ndis), I need to power-cycle the laptop.
When it occurs again, I will get you the details and the full dmesg. Do
you want a verbose dmesg, or a standard one?
