Yep, I've upgraded to 2.5.21, and this was fixed. Thanks.

I tried quickly, and it seems to be even worse.

More news...
After spending some quality time with my motherboard, I
managed to get the OHCI and UHCI card on their separate
interrupt. I'll blame Christopher Hoover, because it happened after I
lent him my OHCI card ;-)
Anyway, getting UHCI on it's own interrupt seem to have fixed
all UHCI problems. Both uhci-hcd and usb-uhci-hcd work perfectly under
my stress tests with 2.5.20 (two dongles, SMP). I didn't do any perf
tests (latency, latency, latency !).
In 2.5.21, it's working fine so far, apart that once I got the
following :
------------------------------------------------------------
usb-uhci-hcd.c: Detected 2 ports
usb_control/bulk_msg: timeout
usb_control/bulk_msg: timeout
usb.c: USB device not accepting new address=2 (error=-110)
usb_control/bulk_msg: timeout
usb-uhci-q.c: Watchdog timeout, defibrillating...
Expect disconnections...
=> total freeze of my PC
-------------------------------------------------------------
So, I guess you just need to defibrillate the defibrillater ;-)
Now, back to OHCI. In 2.5.21, things are somewhat different
than in 2.5.20, and it fails even before the IrDA driver enter in
action. The full log is below.
I also tries 2.5.20 on the same box with a non-SMP kernel, and
that didn't make any difference.
Yes, I know about Opti bugs. It's just that it used to work...
Thanks again for the hints...
Jean
