Subject: zaurus: mmcblk0: error -110

Hi!
When I insert the mmc card to zaurus, it gets properly detected and prints some
info into console. Mounting reading/writing files works fine.

However when the card is removed (doesn't need to be mounted before), the
removal is most likely not detected, so when I insert it again, no info is
printed into console and moreover when I try to mount it zaurus goes into
infinite loop printing:
