           Summary: [REGR] RV635 GPU lockup after enabling unmappable VRAM
                    V2 (KMS, Radeon)
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: astronomo@op.pl

kernel log with the backtrace

I have tested recent branches drm-radeon-testing (last commit
7a1ffce50373c177d3f6eecce52badc40c90e1dd) and drm-next (last commit
9e51159c14c29ebd485a45ba56f148e180d62c29) from
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git.  These branches
contain patches for enabling unmappable VRAM. However, soon after booting I am
getting a GPU lockup and corrupted console and X.

My hardware is laptop ASUS M50SA with 4GB system memory, and graphics 1GB
Mobility Radeon HD 3650.

I am attaching the kernel output with the backtrace and lspci -v output.
