If you have not read the entire thread, once the laptop keyboard and

Weirder and weirder :-(.
Something with SX locks? Hmm. I do use those for attach and detach for
RNG sources. Could it be that that stick of yours is somehow getting
involved in the RNG source locks?
It's not limited to a single usb device. Plugging in/Unplugging
a logitech mouse dongle, the memstick, a Western Digital MY Passport
external usb hard drive, all lead to the locked keyboard and video.
I tried adding both RANDOM_DEBUG and USBDEBUG to the kernel, but the
mount of output is mind numbing.
Can you enter kgdb when the usbconfig is froozen, and backtrace all
kernel threads. You should see exactly what locks are the problem.
Maybe some lock didn't get properly unlocked!
