AR5416/Soekris instability

There was no crashdump to provide - so I didn't.
I had a log of a period with no traffic as well but I lost it due to  
the crash.
I'm recompiling the kernel with the debug options now. Will retest tomorrow.
This is a Soekris net5501 with a TP-Link TL-WN951N W-LAN PCI Adapter 300 MBit.
I haven't tested many different kernels but I know 9-STABLE doesn't  
work - no one can associate - that's why I went to HEAD.
Sorry, for being brief, but it's getting late here. ;)
Alex.
