Re: Bug#687136; graphics corruption with Radeon 6570

[Jim McCloskey <mcclosk@ucsc.edu>]

Hello. Following an install of wheezy using debian-wheezy-DI-b2-i386-netinst.iso, I
reported bug #687136:

   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687136

concerning xserver freezes with corruption of the screen at every boot. The GPU
is identified thus:

  [AMD] nee ATI Turks [Radeon HD 6570]
  Subsystem: XFX Pine Group Inc. Device 3190
        Flags: fast devsel, IRQ 16
        Memory at d0000000 (64-bit, prefetchable) [size=256M]
        Memory at fe7c0000 (64-bit, non-prefetchable) [size=128K]
        I/O ports at b000 [size=256]
        Expansion ROM at fe7a0000 [disabled] [size=128K]
        Capabilities: [50] Power Management version 3
        Capabilities: [58] Express Legacy Endpoint, MSI 00
        Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?>
        Capabilities: [150] Advanced Error Reporting

The bug was originally reported against firmware-linux-nonfree, but was
reassigned to linux-image-3.2.0-3-686-pae.

I've been doing my best to investigate since then and found some sources which
suggest that 3D support for this card was added only as of libdrm_radeon-2.4.34.
As far as I can tell no version more recent than libdrm_radeon-2.4.33 is
available in any Debian repository. 

Would it be possible for someone here to confirm or disconfirm this conjecture so
that I can correct/update the bug report?

Thanks very much,

Jim

PS If there is a way for me to hand-compile a more recent version of
   libdrm_radeon that might allow the machine to boot without freezing up, I
   would really appreciate a link or some pointers.
