Subject: [BUG] ipaq USBserial driver

Hi.

Havent had time to track this down but the ipaq.c driver seems to have a
problem since about 2.5.57 or so.

I get repeatable stiffing of 2.6.0-test3 if I place my toshiba e750 in
the cradle while ipaq.ko is loaded. if it isnt loaded the machine is
fine. Im using uhci-hcd.

the e750 needs ipaq.c too be modified btw. (its prod id is 0x0409 not
0406 as is the toshiba e740).

Can you try using the nmi watchdog to see where the kernel is locked up at?

Try sending a patch to the author/maintainer of this driver.
