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
