mtrr ??

[nacnud]

I've finally gotten through the install, rebooted, and after the kernel loads the system hangs at the following line:

mtrr: 0xd80000000, 0x1000000 overlaps existing 0xd8000000, 0x00000

What does this mean? What is "mtrr"?

The above line comes right after a bunch of vesafb lines, the last of which is

vesafb: scrolling: redraw


I'd appreciate any help. I'm almost there.....

what are the arguments your are passing on the kernel command line ?

[nacnud]

Sorry, do you mean the arguments I'm passing to the kernel in grub? The only one is video=vesafb (I'm using 2.6.9 kernel).

[fennec]

have you tried using the vga= argument ?

[fennec]

you can use the following settings

[nacnud]

Thanks--I'll try this and report back.

I noticed that some people include mtrr in their arguments. Do I need to do that?

[fennec]

i dont yet use it because i did not have time to read about it, but it supposed to enhance framebuffer's performance

[nacnud]

Hmm, I entered vga=794 and though I do get past the previous hang I now get the message that I "passed an undefined mode number."

[fennec]

sorry my mistake those were older settings, you should use the following =P

[nacnud]

I'm still getting the "passed undefined mode #" message. When I press the space bar to continue, it hangs at the original mtrr line again.

What does mtrr stand for, do you know?

I was following the directions in the installation guide, but is there an updated source that you drew the vga modes from?

[sorooros]

MTRR stands for Memory Type Range Registers.

As a quick fix you can try passing following to the kernel:

[nacnud]

Thanks for the ideas. I tried the video=vesafb:nomtrr and now it hangs on the line just before the mtrr line on boot; there are eight vesafb lines leading up to the last one, where it stops:

You need to disable framebuffer in kernel and then recompile it.
