Problems with CompactFlash reader on Thinkpad x31

[Tomas Krag]

This is a problem that started when I upgraded from Ubuntu Hoary (5.04) to
Ubuntu Breezu (5.10). I have since performed a clean reinstall of Ubuntu
Breezy, and the problem persists. 

I actually just wanted to see if anyone out there can confirm this problem
so that i can at least eliminate faulty hardware as the cause.


When I insert a Compact Flash card into the built-in slot on my IBM
Thinkpad x31 behaviour is strange.

The first time I insert the card after a reboot, it is recognized and mounted
correctly, and the icon appears on the desktop.
After unmounting and removing the card, the strange behaviour occurs. If I
reinsert the card (or a different card) a second time, the device is
recognized, and mounted, and the icon shows up for a fraction of a second,
but then the card is instantly unmounted again.

When this happens, I can sometimes get the card mounted as root, either
through the command-line or using gnomes disks-admin utility. However
equally often the disks-admin utility will freeze in this situation, and
any further attempt to access or mount the device seem to freeze. Once in
this state, I cannot mount usb devices or anything else for that matter,
and if I try to shutdown the PC, the shutdown process freezes partway, and
I need to hard reboot it.

Also, once the laptop is in this state, i.e. after mounting and then unmounting
a compact-flash card, other tasks, such as suspend-to-ram (or more often,
resume) are also likely to freeze up the laptop.

I have filed this as a bug report on ubuntu's bugzilla, but just wanted
to see if anyone else has experienced this type of problem, either on a
thinkpad x31 or with different hardware.  

My uname output is:
Linux tkragX31 2.6.12-10-686 #1 Fri Nov 18 12:09:04 UTC 2005 i686
