FC3 system hangs after inserting USB stick

[Stefan Behrens <sb2004@freenet.de>]

Hi there,

I have repeated problems with a hanging FC 3 system after inserting
a USB 2.0 memory stick. Sometimes I just cannot mount the FS, sometimes
the whole machine hangs when trying to mount. In such case, none of the
Ctrl-Alt keystrokes works. I had to press the reset button on my box.
I'm running FC 3 with stock kernel 2.6.9 and udev upgraded to
udev-039-10.FC3.1.i386.rpm.

However, this does not seem to be a 2.6 problem, I had similar effects
with the same stick on a notebook running 2.4.27 (upgraded FC1).
In one case even the power button didn't work and I had to remove the
battery ....

I tried formatting the stick using WinXP and also tried mkdosfs but with
no effect.

Here is a trace, inserting the stick (fails), removing it, inserting it
again (worked the 2nd time). Note I did not mount the device at all to
produce any of the errors and printouts.

Any idea? This really shouldn't happen.
