Summary: Unplug MMC card from SPI-MMC daughter card, system hangs and takes long time to recover.
Plug in a MMC card in SPI-MMC daughter card, the card can be detected.
Then unplug the MMC card, system will not respond for a long time. It may take half minute or longer to respond to key input in the console.
It's OK for SD card that I tested. This happens both in trunk and 08r1 branch.

When unpluging the MMC card, the card detect handler will call
spi_mmc_revalidate() 'immediately', this cause the console not response. Now

I validate with all SD/MMC cards and found it fails to detect all my SanDisk SD
cards when I plug them into SD slot after kernel boot up.
Plug it to SD slot before kernel boot up, it can be detected.

SanDisk SD cards auto detection problem is not related to this bug. I will open
a new one.
This bug is fixed. Close it.
