Hi,
I have a problem with Marvell Libertas SDIO card in my HTC Shift UMPC.
I tried many kernel configurations, but the card is never detected. However, I found in the Internet that this card works in Tinycore Linux 4.x. Indeed, when I booted Tinycore from USB, wifi was working.
To further test it, I compiled their kernel only changing the configuration to enable dm-crypt. Surprisingly, card was detected and the firmware was successfully loaded. Unfortunately, system is completely unusable with this kernel. I only managed to dump dmesg from console.
Could anybody help mi with kernel configuration?

Dmesg from my 3.17.1 kernel: http://pastebin.com/EYsdUN1k
Dmesg form 3.0.3-tinycore: http://pastebin.com/nL24nYgr
My config: http://pastebin.com/Y4zmW5cJ
Tinycore config: http://pastebin.com/Y3sm9uej

Regards,
Przemek
