Of course. My monday-morning bad temper is over by now, and I hope I
didn't transfer it to any of you. I'll provide the panic, one way or
another.
Can you reproduce the problem on a non-RT kernel?
No, it only occurs with RT kernels, and only with those configured for
PREEMPT_RT. If I use PREEMPT_DESKTOP, there is no problem. (with
threaded IRQ's etc... only switched over the preemption level in the
kernel config).
I've uploaded the photo's of the panic here:
http://freebob.sourceforge.net/old/img_3378.jpg (without flash)
http://freebob.sourceforge.net/old/img_3377.jpg (with flash)
both are of suboptimal quality unfortunately, but all info is readable
on one or the other.
Can you add debug printk's before and after tasklet_kill() in
ohci1394_unregister_iso_tasklet to see where it locks up?
That's the first thing I did: the printk before tasklet_kill succeeds,
the one right after the tasklet_kill doesn't.
