Somebody probably forgot to release a lock.

And the somebody is probably one of those tainting modules. I believe 
this is stuff from:

http://stefan.endrullis.de/en/xilinx_ise_7.1.html

Right? Looking at the linuxdrivers.tar.gz tarball I see binary archives 
meaning we can't help with that here -- we don't have the source to look 
for the problem. Any and all support will have to come from whomever 
supplied you with it.
