Hi, we're having trouble getting SDIO connected harware to fly on MX31 based designs. In particular, a SD8686 chip supported by the libertas_sdio driver will hang forever when built without CONFIG_MMC_DEBUG=y. With that option selected, however, the behaviour is a little different, and I can at least see the following messages on a recent 2.6.32-rc5 based MX31 tree. Is there any common pitfall for such setups? I did more or less the same thing on PXAs (same WLAN chip, same kind of interface, same firmware), and haven't seen any such effects, so I suspect the MXC specific parts to be the reason for that. Any ideas?
