SubjectUSB lockup in 2.4.18-pre8
Hello,

beginning with 2.4.18-pre7 I notice a complete system lockup using a SANDISK
SDDR-05 compactflash USB adapter.
I used the device in earlier kernel versions with the "UHCI Alternate Driver",
but in 2.4.18-pre7 I experienced a complete system lockup when mounting the
flash card. So I switched over to "UHCI (Intel ..." device, which worked ok in
2.4.18-pre7.
Unfortunately starting with 2.4.18-pre8 I had to find out that now both
UHCI-drivers produce the lockup. Since I did not find any hints in lkml from
others I thought it might be worth dropping a note...

I am willing to try out whatever is necessary.

Regards,
Stephan
