I have a nice USB-2-capable compact flash reader that works perfectly on
my EHCI system, and that I've also verified some time ago on an UHCI setup
(but hey, the UHCI part could have rotted over time).
However, on a HP laptop I have with an ALI southbridge, the USB subsystem
dies badly whenever I insert the card reader.
It looks like usb-storage, scsi_eh_0 and khubd are all dead. khubd is
waiting for the completion of the SCSI "check_disk_change()" call, which
never completes.
The following is the output of the USB initialization, USB storage (with
debug on - the only event is the insertion of the device), and the
backtrace of the hung processes.
Ideas? Anything that stands out except for the "babble" thing?
