Sorry to bother you, but I wanted to give more details about
the crash. It took me a bit of trying to get my box to not instantly
freeze.
Hardware : PPro 150MHz SMP, VIA UHCI add-on card, one IrDA-USB dongle
Kernel : 2.4.11
Patches :
o Timeout fix you sent me
o Other fix mentioned there :
http://www.geocrawler.com/lists/3/SourceForge/2571/0/6795975/
o Add 2 printk() in strategic places
Behaviour :
After the first packet sent to the dongle, things go very
funky. I've got this weird error message and all my URB timeout. Then,
when the uhci module is remove, I've got a nice oops.
The log is attached...
Take your time, there is no hurry...
Good luck...
