Having issues here with ath9k, much slower than it was with 2.6.37.
Found this bug re: Ubuntu on Launchpad, haven't checked the kernel
tracker: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/735171
Looks like I'm also getting bit by this on another machine that uses
ath5k. Watching wireshark on two machines, almost all packets sent to
the ath5k card never make it with 2.6.38. I also tested with a
compat-wireless tarball from 2011-03-18 with the same results.
Reverting to 2.6.37 makes the issue go away. Definitely seems like an
unsafe upgrade at least for Atheros users.
I can confirm that. When running 2.6.38 my downstream with ath9k is about 13
times slower compared to 2.6.37.4.

What kind of network are you using? A person in IRC suggested that
these issues might only exist on certain (relatively rare) networks,
like 802.11n or ad-hoc.
It is a 802.11n network and they aren't that rare today. Every access
point in my neighbourhood is using that standard. I'll try to reproduce
the issue after switching my access point to 802.11g only.
