Kernel 2.6.20+ and rt2500/rt2570 problem

Kernel 2.6.20+ and rt2500/rt2570 problem

[Wiktor Wandachowicz]

Recently I tried newer releases of Linux distributions, specifically
Sabayon Linux 3.3 and Ubuntu 7.04. Both suffer from problems with
rt2500/rt2570 modules not being able to associate with access points.
There are numerous problems reported Ubuntu Launchpad, Gentoo Forums
and Sabayon Forums.

Please, Linux kernel developers, try to help out the guys at:
http://rt2x00.serialmonkey.com/

They look pretty clueless and don't know exactly what to do.
It seems that advances in kernel to Wireless Extensions 19 broke
their efforts somewhat.

If possible, speed up the inclusion process of the driver into mainline
kernel, so users won't have to be forced to do a hardware upgrade.
Additionally, this problem prevents my machines from being upgraded from
Ubuntu 6.10 (kernel 2.6.17) to Ubuntu 7.04 (kernel 2.6.20 I believe).

With kind regards,
Wiktor Wandachowicz

There are two modules in Ubuntu for this chipset, the rt2500 (default)
and rt2500{pci,usb}. You could try blacklisting rt2500 and use
rt2500pci. See if that helps.
