Summary: [Evergreen KMS] HDMI port output only works with
new_pll=0

Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW

I have an HP Envy 15 with mobility 5830. Laptop panel works fine, however, the
hdmi port connected to a dell 20" lcd produced garbled screen. I tried adding
radeon.new_pll=0 on grub and it fixed the problem.
Using the git evergreen_accel branch xorg ati driver with 2.6.36-rc4 with
airlied's drm-radeon-testing. Xorg version from ubuntu xorg-edgers ppa
1.9.0+git20100902+server-1.9-branch.79ee78de-0ubuntu0sarvatt. Mesa version from
ppa 7.9.0+git20100915.e0b6df4f-0ubuntu0sarvatt.
