But it's a bug. Michal, can you please track this as a post-2.6.22 regression? Others: can you please take a look at the dmesg output, see if we can work out which subsystem is (newly) failing?

With kernel 2.6.23-rc3, this does not happens anymore: - first, at boot, there are some new lines in dmesg saying /dev/sda is seen but size cannot be get (normal: there is no memory card in the reader); - second, plugging the card does nothing; - third, issuing blockdev --rereadpt /dev/sda does not work; - finally, fdisk /dev/sda fails (unable to open /dev/sda). So the device seems to be completly unusable now (this is a Thomson card reader if I remember well). dmesg output for 2.6.22.1-cfs19 and 2.6.23-rc3 appended to show the differences. Steps to reproduce: Maybe the problem is specific to my hardware. I presume: boot with an empty card reader connected, the plug the card and see it is inaccessible? I'm struggling a bit to work out if this is a scsi bug, a USB bug, an MMC bug or whatever. But it's a bug. Michal, can you please track this as a post-2.6.22 regression?
