[haiku-development] timeout in acquire_sem_etc not working

Hi all,

I'm trying to debug the IDE stack and located a deadlock during boot on some 
systems in scan_device_int().

It is doing a call to acquire_sem_etc with 100ms timeout, that never returnes. 
How is this possible?

I enabled IDE irq and semphore debugging, the full debug output is available at 
http://overhagen.de/haiku/haiku-idedebug.txt

The relevant debug output is the last line of "switch_sem_etc: setting timeout 
sem for 100000 usecs, sem 1290, thread 7" but there is no "sem_timeout:" for 
that thread. Concurrently, thread 5 does a 100ms timeout that works fine.

regards
Marcus
