Hello.
I've got a laptop with the above WiFi card.
I just upgraded to 14.3 in order to see if stability and/or speed could
improve.
For stability, time will tell.
As for stability...
Today I rebooted the AP I was connected to: with 14.2 probably I would have
experienced a panic; with 14.3 however I was simply disconnected.
After a while, all the other devices were back online, but my notebook was
still without any WiFi association.
I tried "service wpa_supplicant restart", but it didn't help; so I issued
"service netif restart" and everything hanged.
I tried typing some DDB commands without seeing anything and I ended up with
the following backtrace:
is this from core.txt? What's the panic message?
Also what's /usr/src/sys/compat/linuxkpi/common/src/linux_80211.c:2364
for you (a few lines before/after maybe as well)?
Also if you have a core.txt, can you check the kernel message buffer if
there was a firmware crash before this and the panic is a secondary
issue?
I noticed that I have a 9xxx in a laptop I am currently using to test
suspend/resume with. I'll give it a bit of pushing over the next
nights and see.

I don't have the sources available now, as I'm out of office, but I'll give
it a shot at getting better info when I can.
Please let me know if you want me to check anything specifically.
bye & Thanks
