I think some of the reports on kerneloops are from my machine, I'm
running wireless-testing#master in the hope to get my card fully
working. It's a AR2425 chip (MAC: 0xe2, PHY: 0x70), in a Lenovo Notebook.

The wireless-connection is nearly unusable. I can provide access to this
machine or test patches if anyone can help.

I get many warnings like
