Re: function call fw_iso_resource_mange(..) (core-iso.c) does not return

An important note with case b) is that Ralf (the original reporter) was
running 3.4.something. I'm aware that some work has gone into workqueue
locks in 3.9 and 3.10. I asked Ralf if he could reproduce on a more
recent kernel but never heard back. Maybe these are two different problems
(ie, a failure to guarantee forward progress on a single workqueue and
a straightforward deadlock when using two wqs)?

Stephan Gatzka,
what kernel version did you instrument and reproduce this with?

Ralf and I are working together on the same system. It's kernel 3.4.28, patched with Xenomai 2.6.1.
