Subject: No MMC device recognition after suspend

Hi there,

I found out that the "17ef:1003 Lenovo Integrated Smart Card Reader" does no
longer detect an inserted SDHC card once the box (T510) has been suspended.
After reloading udev the device detects inserted cards as it did before. The
behaviour applies to 2.6.37, later versions not tested, as suspend/resume is
currently broken on the box.

There's no logging once the card is inserted and not detected, just mount
stating that /dev/mmcblk0p1 is not present.

Any hints are very appreciated.

Regards,
	Marc
