There were changes to the EHCI driver between 2.4.21 and 2.4.22; maybe they are responsible for what you're seeing. I don't know if it's possible to use the 2.4.21 version of the EHCI driver in 2.4.22, or vice versa -- but it would make a good test. Does anyone else know the answer? I don't _think_ any changes in usb-storage were significant enough to cause your problem, but I haven't had a chance to check and make sure. The "host_reset requested but not implemented" message isn't something you have to worry about. All it means is that the SCSI layer wants to attempt a form of error recovery that usb-storage doesn't support (and never has supported). Of course, if it appears it signals that the error is non-recoverable -- so there will lots of subsequent I/O errors, as you saw.
