Yes, on real M5208EVB hardware. That is what I ran it on.
I didn't run it under QEMU.

Better to use the fixes to QEMU instead of working around
its problems in the linux kernel sources :-)

This thread has the QEMU fixes:

https://lists.nongnu.org/archive/html/qemu-devel/2014-08/msg03224.html

I have posted them a couple of times to the QEMU dev list, but
no-one seems to pick them up.

Yes, you still need that. I haven't cleaned that up into a
state that I am totally happy with yet.

Hmm, no, haven't seen that one. I'll try a run with qemu and see
if I can see what is going on.
