Bug#233832: Radeon DRI MTRR problem



Package: xlibmesa-dri
Version: 4.3.0-2

Upon upgrading from 4.3.0 pre-release packages to the recently released 
4.3.0-2 packages (thank you for your hard work!), my direct rendering
stopped working, however the problem has identical symptoms to those 
errors already posted here so I am assuming it is the same sse_test_dummy
missing symbol others noted.

While I was digging for this problem however, I found this as the only
fault in my xfree86 log file (radeon mobility 9000 card, 2.6.2 kernel,
kernel radeon driver):

(WW) RADEON(0): Failed to set up write-combining range (0xe8000000,0x2000000)
(WW) RADEON(0): Cannot read colourmap from VGA.  Will restore with default

(don't know if the second one is new or old.)  Matching this, the 
following appears in dmesg:

mtrr: 0xe8000000,0x2000000 overlaps existing 0xe8000000,0x1000000
[drm] Initialized radeon 1.9.0 20020828 on minor 0
mtrr: 0xe8000000,0x2000000 overlaps existing 0xe8000000,0x1000000

I included the [drm] message to show the exact context of messages appearing
in dmesg--they appear exact in the order show there, with no other lines
between.

cat /proc/mtrr yields the following:

reg00: base=0x00000000 (   0MB), size= 256MB: write-back, count=1
reg01: base=0x10000000 ( 256MB), size= 128MB: write-back, count=1
reg02: base=0xfeda0000 (4077MB), size= 128KB: write-through, count=1
reg03: base=0xe8000000 (3712MB), size=  16MB: write-combining, count=1
reg04: base=0xf0000000 (3840MB), size=  64MB: write-combining, count=1

I'm attaching the XFree86.0.log file; my XF86Config-4 has nothing
interesting in it so I'm not wasting bits with that.

thanks again for the hard work,
take care
