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@lists.freedesktop.org ReportedBy: peterle@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).
