USB 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

Can you try compiling the usb-storage driver with the "Debug messages" option enabled? Then send the log file and info to the usb-storage author/maintainer and the linux-usb-devel mailing list? That's a better place for questions like this.

thanks,
