[Solved] radeon module freezes system with dpm enabled

Hello,

I have been running my Radeon HD 5770 with xf86-video-ati (1:7.5.0-1) for quite some time now without any issues. Yesterday, I upgraded mesa and my system started to freeze with a black screen during boot. Blacklisting the radeon module allowed me to boot my system. Attempting to load radeon on a running system will also result in a black screen and a frozen machine. I was not able to recover any log output from the radeon module. Downgrading mesa did not resolve my problem.

Booting the kernel with radeon.dpm=0 seems to work. The fan noise is reduced by using dynpm for power_method. However, it would be nice to resolve this issue!

I'm running 3.18.6-1-ARCH. The mesa update:

Re: [Solved] radeon module freezes system with dpm enabled

I also experienced this problem when booting the Arch live cd. While the system was frozen, I moved my monitor's DVI connection to the other connector on my card. Suprisingly, the system became unfrozen and continued booting the live cd. Now the issue seems to be gone and I can boot from my harddisc with radeon.dpm enabled.
