[solved] 3.0-ARCH and rt2500pci kernel panic

After upgrading to kernel 3.0 I began to get this message in my kernel log pertaining to my wireless card:

kernel: [32460.800014] phy0 -> rt2500pci_set_device_state: Error - Device failed to enter state 1 (-16).

And shortly after connecting to my wireless network the kernel would panic and become unresponsive. I installed kernel26-lts and still receive the message but no panic. I discovered that if I run:

iwconfig wlan0 power off

The error messages stop and I don't receive any kernel panics, and I can run with the 3.0-ARCH kernel no problems.

k6b@archdesk ~ % lspci | grep Network
01:08.0 Network controller: Ralink corp. RT2500 802.11g (rev 01)

I was going to post a bug report but wanted to check here to see if there is an easy way to solve this issue so I'm not cluttering up the bug reports with something that doesn't belong there. I know how to fix the issue but I don't want to have to babysit my computer each time it boots and then run that command in a terminal before it connects to avoid a kernel panic. Has anyone else experienced this issue with the Ralink wireless cards? From what I understand the rt2x00 driver is compiled into the kernel and it "should just work"

Thanks in advance for any help, I will be more than happy to provide anymore information required.

you can use the method mentioned in the last point of the misc. notes on the above page to make the "power off" as a default

seems the power managerment often causes problems

Thanks tom.yan, that did the trick! I don't really need power management anyway since this is a desktop.
