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!
