[Jaunty] rt73usb from backports locks up system

[Psy[H[]]

installed 9.04, 2.6.28-11.42-generic i686
Asus WL-167g adapter using rt73usb module.
System goes to hard freeze after 1-2 minutes adapter plugged in. All usb ports are partially powered down, keyboard in not responding.
Nothing wrong is recorded to logs. Syslog is in the attachment and there is no dmesg log of the time adapter was plugged in.

Situation does not occur when using adapter under 9.04 RC live system.

This is another recidivation of rt73usb module malfunction, it blocked sudo and caused other strange malfunctions on Hardy, kernel panic on some kernel versions on Intrepid, and now - total freeze on Jaunty.
As previous situations were more or less resolved, I think this is time for new bugreport and deeper analysis of this malfunctioning and dangerous module.

Update: looks like faulty module is in the linux-backports-modules-2.6.28-11-generic package. After it's removal my system functioned with adapter and without freeze for some 10 minutes and still alive.

I have the same problem with the rt61pci driver. I've also tried manually compiling some of the more recent the compat-wireless packages and it still happens (the ones after 2009-13-04 do not compile so i don't know if it has been resolved). The ath5k from both backports and compat-wireless is working fine so i think the problem is only in the ralink drivers. There are no logs or anything - the system just freezes after a few minutes even if there is no network load.

I've just experienced full hangup without backports modules installed. It was a single event, I could not reproduce it.
As with backports' module hangup, there were nothing in the logs, but this time usb was not powered down.
So, the main version of ralink modules is also risky to use.

same here... first time i had such a problem. the irony is that i chose the specific adapter so that it would be Linux compatible. I just installed jaunty and it freezes after a few minutes of use. Can anyone help?

I don't have any problems with Jaunty's default driver (rt61pci ver. 2.2.1). I experience lockups when i use the newer driver (ver. 2.3.0) which is used by the backports package, compat-wireless and newer kernels (2.6.29 and 2.6.30). There are some threads about similar problems on the rt2x00 project's forums (http://rt2x00.serialmonkey.com/phpBB/) it might be useful to report directly there.
