I do not think there was any messages about the disk before. It seems to happen
only once when I
used your patch. Somehow it makes the disk and USB drivers interact. Also, I
was able to use USB
with or without your patch in about the same way: 1) trouble to connect but
sometimes it does
connect when USB device is inserted; 2) when it is connected, after a few
minutes (the longest USB
uptime I had was 1 hour) either the communication slows down to the level that
it is almost
impossible to use or USB completely disconnects.

Currently (I returned back to 2.6.15.1 unpatched kernel):

I'll take a look at the next attempt.

Not sure if the crashes happened without USB devices. I'll experiment more some
time later.
I wonder though if those crashes might damage hardware?

I'll try that tonight.
Might it be that we are on the wrong track here and it is not a
kernel/module/driver but a
configuration problem? What are the relevant configuration files to check?
Also my system has so many different USB devices: webcam, bluetooth with
wireless, 4 USB ports, 10
in 1 card reader (which I disabled in Bios for now) and probably something
else... Might they
interefere with each other somehow? Maybe some kernel parameters might help?
Thank you,
Igor
