Problems with SD8686 SDIO on HTC Shift

[Sven Barth]

Hello Dan!

Thanks for your answer.

Yes, I did indeed mean 2008. ^^

The SDIO Controller seems to be a no-name one (at least if I found the 
right one). I used "lspci -vvv"  and the output is attached.
I also found some output about the SDIO controller in dmesg (see 
attached file). Might the problems reported there be the source of the 
timeout problems?

I also removed the part about TX_POWER from main.c, but now the module 
hangs with CMD_MAC_CONTROL (0x0028) (another clue, that the source of 
the problems is the SDIO controller?)


Thanks for your help.

Regards,
Sven
