It certainly would be worthwhile getting some debugging logs for comparison on that. 2.6.14-rc2 and 2.6.14-rc3 don't differ by very much. > The pen drive. > > > I was unable to download them (error 404). > > Sorry, my mistake - it's in > <http://www.cs.tau.ac.il/~didi/kernA.log> > <http://www.cs.tau.ac.il/~didi/kernB.log> > > I can also report that it works with 2.6.8-rc1 and does not work with > 2.6.8-rc2.

Or at least the portions that changed between -rc1 and -rc2. However I'm not completely convinced you'll find anything. Those "Medium not present" messages in your log should never occur with a flash device. They indicate a hardware or firmware problem. It might turn out to be something trivial, like your B machine doesn't provide sufficient voltage or current on the power connection of the USB bus. Also keep in mind that sometimes failures occur at random. You might get fooled into thinking a particular kernel release is at fault, simply because by pure chance the previous release ran okay in your test.
