I made some progress in my attempts to make a Marvell 8686 work on an
AT91SAM9263 board. I use latest netdev-2.6.25 plus a patch that solves
the modulo-4-problem of the AT91 MCI driver. That patch was recently
posted by Marc Pignat on linux-arm-kernel ML.

ATM, firmware is downloaded without problems. But after that, it hangs
somewhere in libertas core code. The last thing I see is:

libertas: 00:19:88:05:1c:53, fw 8.73.7p3, cap 0x00000393
libertas: Command 28 timed out
libertas: requeueing command 28 due to timeout (#1)

This is somewhere in lbs_setup_firmware(), called from lbs_start_card()
in libertas/main.c.

Could somebody tell me what the above messages mean?
Are there any other users of similar hardware out there?
