           Summary: Slow text scrolling on tty after suspend-cycle
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: peterle at hottemptation.org


Hello,
I upgraded from kernel-2.6.37 to kernel-2.6.38-rc6 today, before that upgrade
the bug was also present but only sometimes (1 in 10). Because this now happens
while after every suspsend-cycle this is definitely reproduceable. When I
suspend with "pm-suspend" and resume the computer from suspend, the scrolling
on the tty windows is extremly slow.

Reproduce:
1. Use a tty with KMS
2. #pm-suspend
3. resume from suspend
4. launch a command which requires to scroll the output on the tty, like
"dmesg"

Other applications also draw "slow" like fbi (part of fbida, a imageviewer for
the framebuffer).
