The same on Acer W500. Driver blacklisting solve problem, but native resolution became unavalible.

The same on a desktop with Radeon HD 5400/6300 Series card. Since a few revisions it only boots in safe video mode. I am testing hrev47213.

If this is a recent issue, could you try an image hrev47187 or earlier to see if you still have trouble?

comment:5 by vercu, 10 years ago

I installed hrev47185 and my computer boots without using safe video mode. The Radeon driver for HD5450 (Cedar) is in use.

I have the same bug, booting with Radeon HD 7850. Only boots in safe video mode. It booted normally in hrev47149-x86gcc4hybrid. It started when I tried hrev47196-x86gcc4hybrid.

I think I have this one solved. The recent change to pll's makes too many assumptions that the spread spectrum data is valid and can divide by 0. Should be testing the solution shortly.

Should be fixed in hrev47257. Please give it a try and let me know. Keep in mind that radeon_hd is broken on 64-bit atm (#10614)... so limit your testing to 32-bit images.

Tested hrev47259: It now works again. The Radeon card is in use. Thanks a lot for fixing this.
