mtrr: no more MTRRs available
Hi . I am receiving the above message on Red Hat 4 running on ProLiant DL380 G3 server.
Please help me figure out what it means. I understand what the MTRR part is ( after reading wikipedia ) but it did not help much in understanding why the message comes out.
Regards,
Leonid.

I once tried to figure this out. I did not succeed, but I remember it had something to do with X, and since I was installing a server I stopped spending too much time finding a solution for something that was not a problem to me. Nice WIKI article, by the way.

It's because you are out of MTRRs. It has to do with memory holes and BIOS (I have not looked at the Wikipedia page so forgive me if that's what you already know)
I've never really seen much on "fixing" it (seems that it's more of an issue on laptops and devices that share RAM with a GPU) but you might try messing with the AGP "memory hole" option if it exists in the BIOS. I assume your BIOS is the latest-n-greatest.
This may offer some insight into altering the MTRR use in the OS:

....but there's likely LOTS of options not mentioned there (case in point, I think write-back is the more common config type)

Re: mtrr: no more MTRRs available
I had this problem on a Proliant ML310. I was also seeing messages about "wrong FS type" "bad option" and "bad superblock."
I got around it by clearing the RAID controller information, creating a default configuration, then installing using Fedora 7.
At the beginning of the process, still in character mode, Fedora 7 (unlike 8 and 9) loaded two drivers that began with "pata..."
