No, no news at all.
I tried the developers list of the driver, but no response either.
It looks like it is a reintroduced bug. I do not have the time to test
compiling the driver and applying patches, in fact the laptop is now a

Hi Lukasz,
I get exactly the same errors in dmesg as oguzy (I copy his, as my laptop has

Spatialist, do you get TX DMA error in your syslog? If not please check

This problem still holds for Kubuntu 11.10, i am attaching the log
files related with the issue. I can see that the ath9k driver is
installed but the error messages continue at the boot up.
Removing the driver, reinstalling it or reinstalling it with the
nohwcrypt=1 didn't solve the problem.

ath9k on Ubuntu 11.10 with 3.0.0-12-generic-pae is 20x more reliable for
me over the last 7 days since upgrade. I have Acer Aspire Timeline X

@Christoph: Thanks for testing. You don't have to uninstall the old

exists. So whether or not you get the messages in earlier builds is no
indication of whether
The error message does not appear with this kernel.
But the connection still disconnects.

There's a report on the upstream bug report that this worked fine in
2.6.37, in which case we can do a bisection to determine which commit
introduced the problem. First, can someone install the kernel at the
following link and verify that the problem is not present? Thanks!
