This is a followup on my attempt to use b43 (now from 2.6.34-rc6) on
a HP Pavilion dv6-1300sb.
With 2.6.34-rc6, I have not had any boot problem (blocking around ssb/b43)
so far.
But, dma mode gives an error (like before) and driver now switches
automatically to PIO mode (new).

During the switch, the led switches from blue to red and returns to blue
after some seconds. Touching the led switches the hardware blocking on
and off, but the led color does not change.
I then tried with the broadcom supplied hybrid driver, and there the
touch/led functionality works as expected : led is red whenever
I touch the button (enabling hardware blocking) or when I issue
a rfkill block 0 (enabling software blocking). Led is blue only when
both blocking are disabled. But, hybrid driver does not give monitor
functionality :( (and of course, also no injection).

Any idea on what I could do to debug more / fix the dma and led problems ?
