I have installed Gentoo 2.6.19-r5 using the instruction in the handbook (http://www.gentoo.org/doc/en/handbook/handbook-x86.xml).

When I reboot for the first (and subsequent) times it locks up after

Code:
  Booting 'Gentoo Linux 2.6.19-r5'

root (hd0,0)
  Filesystem type is ext2fs, partition type 0x83
kernel /boot/kernel root=/dev/hda3
    [Linux-bzImage, setup=0x1a00, size=0x305a67]

Uncompressing Linux... Ok, booting the kernel.


I am using a EPIA-M (ME6000) motherboard.

Possibly due to an illegal instruction, your CPU may not be entirely i686 compatible. Your motherboard appears to have either a VIA C3 or a VIA Eden processor.

There are discussions on the CFLAGS settings to use with the VIA processors here.

I don't know the difference between " Esther C5J (Via C7)", " Nehemiah (C5XL)/C5P (Via)" and " Eden C3/Samuel/Ezra (Via EPIA)" but there is a note that "more recent versions of the C3 do support the cmov instruction and hence -march=i686."

You will also have to make the correct choice under
Code:
Processor type and features   --->
    Processor family
by selecting one of
Code:
( ) CyrixIII/VIA-C3
( ) VIA C3-2 (Nehemiah)

Thanks for the help, that worked.

Here is what I had to do.

Edit the /etc/make.conf to look like:
Code:
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=c3 -m3dnow -Os -pipe"
CXXFLAGS="${CFLAGS}"


Ran "genkernel --menuconfig all" setting the processor type to be:
Code:

Processor type and features   --->
    Processor family
        ( * ) CyrixIII/VIA-C3
