--- Comment #12 from Christian Boltz 2007-07-24 16:25:12 MST ---
FYI: I see the very same problem since the last kernel update. And the
workaround from comment #8 (unloading ehci_hcd) makes it working again.
(For whatever reason, plugging in my camera which is also recognized as USB
mass storage does not show the buggy behaviour. Only the cardreader breaks.)

The only difference is at interrupt 10.
(not resetting needinfo since I'm not the desired info provider ;-)
