Problem with 16-in-1 card reader

Sat Mar 11 12:51:40 UTC 2006

My new PC has an internal 16-in-1 card reader connected via USB 2.0. The
device is the Techsolo TCR-1640
(http://www.techsolo.de/product/cardreader/tcr_1640/index.php).
I boot from a compact flash inserted in it and I can mount and unmount
the same CF once the system has booted and has mounted the root
partition from my graid3 array.
The problem arise when I replace the inserted CF with another one (with
different size and filesystem) and try to mount it. Fdisk can correctly
sees the new partition table, but devfs is not updated and I cannot
mount the new media. I tried to issue all sort of camcontrol commands
(rescan the bus, eject and load the device, ...) but the dev entries
remain unchanged (equal as boot time) even if the card is inserted or
removed (camcontrol tur can see if the media is ready or not).
The system is a recent 6.1-PRERELEASE.

Any ideas or suggestions?

Follows some more debug info.

Boot messages if CF is not present:
