#2 Random crashes with ftdi driver

[Anonymous]

Hi. I'm getting random system crashes with the ftdi
driver.
It works for a few minutes (of sparatic data transfer)
and then crahses
the machine.

It crashes because urb->dev is NULL in td_submit_urb
(usb-ohci.c).
I do not think the problem is in the ohci, or usbcore
parts of my USB stack
because all of my other USB devices work just fine.
I've tried
version 1.3.3, 1.3.2, and 1.2.1 and they all crash in
the same way.
Configuration: Dual athlon MPX, 512MB ram.

me too!

I'm getting predictable lock-ups on several fedora machines.
about 10 seconds in during writing a large block of data.

also spurious lock-ups on a debian (sarge) box. only when
running minicom, though.

don't know kernel versions, sorry.
