           Summary: with r300 (rv530) kms loaded cannot suspend kernel
                    2.6.37+ with uswsusp
           Product: DRI
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: hramrach at gmail.com


After upgrading from kernel 2.6.36 to 2.6.37 I can no longer suspend the system
with uswsusp.

The suspend operation hangs with displays blanked before the part when "Saving
image to disk" takes place.

Suspending with "echo disk > /sys/power/state" works but is obviously useless
as the system cannot be resumed.

Upgrading to 2.6.38 does not help, not loading the radeon module allows to
suspend as usual.

A pointer to a repo with Radeon changesets between 2.6.36 and 2.6.37 without
needlessly intermingled changes to other kernel parts would be appreciated.
