[rtl] write to FIFO problems

[Jochen Kuepper <jochen@uni-duesseldorf.de>]

Has anybody else encountered problems writing to FIFOs ?

I am using a FIFO as command queue user space -> kernel space, writing a
command structure there whenever I want to get influence on kernel space tasks.
Sometimes (to me it really looks randomly) the write to the FIFO hangs
(blocks?) forever. If I kill the app and restart it, all further write commands
will show the symptoms - only solution is to restart the system.

Greetings,
Jochen
