Comment 228 for bug 509273

After upgrade to Lucid I had one freeze already. I am on Xpress 200 rc410 chip. The messaging seems to be turned off. My logs are wordless, so I can't tell what happened. I've had some weird issues when kms was on before. With modset.radon=1 option the system would freeze frequently dumping some garbage to the logs bug #489447
Once, I go without radeon modset, no freezes. In my case, the said option provides dri, which when used does let the laptop wake up after suspend. So after trying it again and reporting the results I will turn the kms off next boot. Now I am trying with pci=nomsi, although it is turned off according to the kern.log

There's one more possibility that it is caused by the ath5k module known to freeze, however with useful logs.
