Hello!
If I insert a special USB stick to my computer, udev will go crazy.
The USB stick is a "SanDisk Cruzer" device. It represents himself as a
block device and a CD rom device.
I do not know, how I could help. So pleace have a look at the logs:
/proc/kmsg if I insert the stick:

Attached is a log of "udevadm monitor" when I plugged in the stick,
wait a moment and remove it again. But the messages do not stop...
I have to stop udev and start it again.
uname -a
Linux thor 2.6.39-gentoo #1 SMP Mon May 23 23:11:54 CEST 2011 i686 AMD
Athlon(tm) 7750 Dual-Core Processor AuthenticAMD GNU/Linux
I am using gentoo with sys-kernel/gentoo-sources-2.6.39. Should I test
also a vanilla kernel?
Gentoo package for udev: sys-fs/udev-168-r2
udevd --version
168
I hope someone could give me a hint...
With regards,
Markus
