Public bug reported:
Binary package hint: linux-image-2.6.17-9-generic
Since installing the edgy knot 3 CD I get errors when trying to load the fglrx
driver about
"mtrr: no more MTRRs available"
If I have a look at /proc/mtrr I have
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
reg01: base=0xd8000000 (3456MB), size= 128MB: write-combining, count=1
reg02: base=0xd7fc0000 (3455MB), size= 128KB: write-combining, count=1
reg03: base=0xd7f80000 (3455MB), size= 256KB: write-combining, count=1
reg04: base=0xd7f00000 (3455MB), size= 512KB: write-combining, count=1
reg05: base=0xd7e00000 (3454MB), size= 1MB: write-combining, count=1
reg06: base=0xd7c00000 (3452MB), size= 2MB: write-combining, count=1
reg07: base=0xd7800000 (3448MB), size= 4MB: write-combining, count=1
which is completely different to what I got from the kernel in breezy.
This results in the ati xorg drivers and even usplash not working at all,
and the fglrx drivers being extremely slow.
I have been unable to find any userspace tools that setup the mtrr's so I
assume it
is from kernel changes.
