hi,
I have a 3-com PCCARD, with the AR5413 chipset
I installed 2 days ago compat-wireless-2.6.tar.bz2, on Ubuntu Gutsy,
and everything seemed to work.
I just had in the log 2 or 3 messages:
ath5k phy0: noise floor calibration timeout
but yesterday, when rebooting, I got a huge number of such messages(more
than 100 in the log file), with also
ath5k phy0: ath5k_chan_set: unable to reset channel
ath0: failed to set freq to 2422 MHz for scan
ath0: failed to restore operational channel after scan
and the boot froze. I then removed my PCCARD,
and after poweroff/poweron, I could boot normally.
It seems to be fixed now, as I have no more this problem after
re-inserting the card.
But as I did nothing, I would like to know what might happen:
If this happened once, there is no reason why this would not happen an
other time.
Pierre

I also get this all the time with a 5006E, and ath5k takes quite a lot
(30%) of CPU most of the time. Haven't tried to track it down yet.
Anyone have ideas about the root cause of the problem?

It seems that sometimes noise floor calibration takes longer than
usual. I'll check it out and come up with a patch asap ;-)
