Also, please send plain-text email: I don't see your dmesg on
lore.kernel.org archive because you send HTML email instead.
But anyway, I'm pasting yours from Bugzilla thread instead

Sardonimous,
The critical line is:
Jun 20 18:20:11 askasleikir kernel: b43_pio_tx+0x373/0x390
I certainly have not used PIO for a long time. I expect that your MacBook Pro
should do DMA on the b43. Apple makes wierd hardware, but not likely that wierd.
Does dmesg offer any clues as to what is happening?
If there is nothing shown in the log, you definitely need to do a proper
bisection from the mainline git tree to isolate the change that led to this failure.
ADDED WITH EDIT: I looked at the code and b43 will not be built for any hardware
without DMA, thus it appears that adding "b43.pio=1" is the only way to get PIO
mode. Please check the output of dmesg for PIO messages.
Larry
