Disabling power management doesn't improve the situation with latest
wireless testing
for me. I had a look at the change and it seems simple enough.

The latest vendor driver has a lot of suspend/resume code in it. I
have had a go at
trying to get it running against a current kernel. modprobe works but
ifconfig up results in a lot

rtl8187: EE:cannot submit RX command. URB_STATUS 0
