           Summary: [RADEON:KMS:PLL] frequent colored lines appear on
                    screen
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: roysjosh@gmail.com


Hello,

I'm back again!  This bug is about the same hardware as in
https://bugs.freedesktop.org/show_bug.cgi?id=19960 .  ASUS monitor VH226H, ASUS
motherboard M3A78-E, HD3200 (rs780).

01:05.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon HD 3200
Graphics [1002:9610] (prog-if 00 [VGA controller])

I just upgraded from f14 to f15 (2.6.38.6-27.fc15.x86_64) and some frequently
occurring but not frequent in number colored lines have appeared on my
screen...  they don't necessarily go all the way across the screen either.

I grabbed the "good" registers from bug 19960 and diff'd them to the current
regs:
[...]
258c258
< 00000404    00000002 (2)
---
> 00000404	00000003 (3)
269c269
< 00000430    00910032 (9502770)
---
> 00000430	00da0030 (14286896)
275c275
< 00000448    159ec704 (362727172)
---
> 00000448	1593a704 (361998084)
278c278
< 00000454    6c012003 (1812013059)
---
> 00000454	6c010003 (1812004867)
[...]

Settings these regs gets rid of the red/white/blue/etc lines:
# ./avivotool regset 0x404 0x2 ; ./avivotool regset 0x430 0x910032
OLD: 0x404 (0404)    0x00000003 (3)
NEW: 0x404 (0404)    0x00000002 (2)
OLD: 0x430 (0430)    0x00da0030 (14286896)
NEW: 0x430 (0430)    0x00910032 (9502770)

And 0x43c was already set to 7:
# ./avivotool regmatch 0x43c
0x43c    0x00000007 (7)

Thanks!
