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.

Greets & thanks,

Pieter
