Hi Stefan

Did you try earlyprintk? You might need to recompile your kernel to
enable it.

Looking at the code, i don't see anything obviously wrong. So i think
i would start by looking how many times it goes through the loop in
qnap_tsx09_find_mac_addr() with this patch reverted, and what address
it finds the MAC address at.

Then see what happens with the current crashing code. Is it failing to
recognise the MAC address, and so keep looping around?
