Can't install 11.2 64 bit on an AMD 64 4000+ machine?

I also have this posted to the “Install…” forum.

And before we get started, I have validated the ISO
and the resulting DVD (I actually burned 2 DVDs and
have validated both of them).

You’ll notice “lm” is in the list of “flags” from
the “cat /proc/cpuinfo” command and “clflush size : 64”


Downloaded the 64bit 11.2 iso, burned to DVD, booted up
and get the error message:

“kernel requires an x86_64 cpu, but only detected an i686 cpu
unable to boot - please use a kernel appropriate for your cpu”

What’s up with that?

That’s truely weird. If true it could be an installer bug.

What about the LiveCD? What does it say? Or the Netinstall CD? Another distro, what does that say? Knoppix 6.2 just came out, might be an excuse to try it.

I haven’t tried the LiveCD. However, I’m running CentOS/64
and Gentoo/64.

As it turns out … I went in to the BIOS and selected, “Load Optimized Default”,
rebooted and “voila”, boots up.

I’m still curious why some 64-bit distros worked and some didn’t.

Oh well, onward through the fog …

It may be the version of the kernel that is used.
