I have no idea if it would help, but I had to use Alan Stern's recent
(Jan 27) usb-storage patch to get 2.4 to work on an embedded system.
Perhaps the VT chips are causing similar problems on Intel hardware?
Actually this patch seems to just make usb-storage expect the
correct "urb is unlinked" status code: the one matching an
async unlink (I see usb-storage using async unlinks) not a
synchronous one (which it doesn't seem to use).
That non-EHCI problem that I mentioned could easily be caused
by the bug this patch fixes. Sequence: EHCI bug happens,
request takes a long time, scsi-eh thread times out request
and unlinks. Then usb-storage deadlocks itself, since it's
waiting for a "will never happen" status code. That's the
kind of failure I had observed.
In short: this patch looks very much worth trying!
