Ah well, I suppose it's good to know I'm not the only one. More
incentive for the bug to be fixed perhaps. I wonder if it's something
specific to the UK or Europe.

I didn't know they'd crippled the BIOS like that. I won't be buying HP
again.

No, but I've done it! If you're interested I can look back through my
old emails and find the git SHA code. I can't be 100% sure I found the
right commit, but I tested the "good" one fairly thoroughly. The commit
message said that the changeset introduced support for AR9285.

Same here. At one point I found that I could safely suspend and resume
by disconnecting the PSU before rmmod ath9k but that seemed to stop
working after a while. It might help to also be on battery power when
booting or loading the module though.
