Comment 60 for bug 314928

Hello

I need help...

I have an acer aspire one A110 with Jaunty netbook remix.
I have already modified the kernel to enable MTRR cleanup (I think... how can I check?)

cat /proc/mtrr
reg00: base=0x0fffe0000 ( 4095MB), size= 128KB, count=1: write-protect
reg01: base=0x0fffc0000 ( 4095MB), size= 128KB, count=1: uncachable
reg02: base=0x000000000 ( 0MB), size= 256MB, count=1: write-back
reg03: base=0x010000000 ( 256MB), size= 256MB, count=1: write-back
reg04: base=0x01f800000 ( 504MB), size= 8MB, count=1: uncachable
reg05: base=0x01f600000 ( 502MB), size= 2MB, count=1: uncachable
reg06: base=0x01f500000 ( 501MB), size= 1MB, count=1: uncachable
reg07: base=0x000000000 ( 0MB), size= 128KB, count=1: uncachable

I can't get the fix to work. When I type:

root@joshaf1986-laptop:~# echo "base=0xb0000000 size=0x10000000 type=write-combining" > /proc/mtrr

I get the error message:

bash: echo: write error: No space left on device

My partitions are far from full, I don't know what is wrong.

Please advise.
