hi,

I have the same problem of MTRR:s and kernel 2.6.13.2

With 2.6.9, the system says:

kex@vdr:~$ cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size= 512MB: write-back, count=1
reg01: base=0xd0000000 (3328MB), size= 128MB: write-combining, count=1

but with 2.6.13.2:

kex@vdr:/var/log$ cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size=983552MB: write-back, count=1

Processor type: (I added the mask printouts to void __init
mtrr_bp_init(void) in mtrr/main.c)

eck reporting enabled on CPU#0.
CPU0: Intel P4/Xeon Extended MCE MSRs (12) available
CPU0: Thermal monitoring enabled
mtrr: v2.0 (20020519)
MTRR: size_or_mask = 0xf0000000, size_and_mask = 0xff00000
CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz stepping 03

Please let me know what info would help tracking this down...

yours,
		Jouni
