[Debian-eeepc-devel] rt2860sta freezes after suspend-resume

[Neil Stewart]

I'm running Lenny on an eee 1000HE. I'm using the backports 2.6.30 kernel
(so I can control the fan---see my addition to the wiki) and the rt2860sta
driver for the ralink wireless. The system freezes after a suspend-resume
cycle when I try to re-establish a wireless network connection.

All is well after e reboot. iwconfig reports the right settings for my
wireless network, wcid is getting an IP address, and everything works.

After a suspend and then a resume the wireless network is gone. Further
"ifdown ra0" or "modprobe -r rt2860sta" both freeze the system immediately
and require a hard reboot. Immediately after a resume, I can see that the
wireless settings are lost. But I cannot re-connect as both ifdown ra0 or a
modprobe -r freeze the system. wicd cannot get a connection.

pm-suspend.log does not offer any clues:

Any clues or help to get this working would be really appreciated!
