Summary: Xorg crashes with radeon KMS after resume from suspend if card in gfx Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Keywords: regression Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: hramrach@gmail.com
cards: 220m rv515gl rv530 EG
problem 2: suspend kernel using uswsusp, cancel suspend by key or due to insufficient memory -> X spinning in drm tested on some combination of rv515 / rv530 and kernel somewhere around 2.6.37-2.6.38, EG on 2.6.39 (on 2.6.38 suspend has to be stopped manually, with insufficient memory it locks up)
problem 1: suspend kernel using uswsusp, start framebuffer and splashy/usplash before resume -> unusable graphics tested with some old kernels on 220m and rv515gl, possibly related to problem 2
In general it seems resume can only happen from text mode, not graphics. In response to this Debian disabled splash in early boot.
This is a Xorg regression compared to UMS.
