           Summary: new_pll algo gives flickering LVDS on rv620 (HD 3470
                    mobility) laptop
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: scary.moo@gmail.com


Created an attachment (id=32960)
 --> (http://bugs.freedesktop.org/attachment.cgi?id=32960)
dmesg with new_pll=1

Latest drm-radeon-testing kernel (1 feb 2010), as soon as KMS kicks in with the
new_pll algo, the LVDS picture shows some kind of ripple effect, as if
something was slightly wrong with the refresh rate. Kind of hard to describe..
The effect persists even when starting X. Changing screen resolution doesn't
help. The new_pll has never worked for me since its introduction back in
december (took me a while to find out it was the culprit). Booting with
radeon.new_pll=0 gives me a perfectly usable system.

On a side, probably unrelated note, I can't help but notice that the kernel
(both the working and the non-working versions) finds an HDMI port, but unless
I'm becoming blind my notebook has no HDMI out .. hm.
