           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.
