I have some problems getting a Marvell 8686 to work with an AT91RM9200 
board. The MCI driver is at91_mci, the SD card in slot A works, the 8686 
is in slot B. Kernel is 2.6.32.7 vanilla.

I get 'command 0x0003 timed out' errors after loading the firmware, 
though the MCI driver says it was successful (full log is attached):

mmc0: starting CMD53 arg 92000034 flags 000001b5
mmc0:     blksz 52 blocks 1 flags 00000100 tsac 1000 ms nsac 0
Sending command 53 as 00011075, arg = 92000034, blocks = 1, length = 52 
(MR = 00000301)
Transmitting 52 bytes
MCI irq: status = 00004045, C07F0001, 00000001
Command ready
MCI irq: status = 0000C0D5, C07F8008, 00008000
TX buffer empty
Handling the transmit
MCI irq: status = 0000C0ED, C07F0028, 00000028
Card is ready
-> bytes_xfered 0, total_length = 52
Block transfer has ended
Completed command

mmc0:     52 bytes transferred: 0
libertas: command 0x0003 timed out
libertas: requeueing command 0x0003 due to timeout (#1)

Is is a problem with the libertas driver or the at91_mci?
