Description of problem:
When I try to install Fedora Core 1 x86_64 system hangs with kernel 
panic about to killing idle task. Fedora Core 1 i386 work on the same 
machine without problems.

Hangs arise at any time of installation process but before any dialog 
(except media check dialog).

I try noapic, apic, mem=xxx boot params, text, graphic and expert 
installation mode. Result was the same everytime.

Looks like bad hardware, specifically the CPU. Something in the higher
oreder bits of the registers (?), since i386 kernel works.

Comment 5 Tomas Dobrovolny 2004-03-29 13:58:56 UTC
It is look like a good idea. I try to found some AMD Athlon 64 CPU
test tools on AMD site, but I have not find any. Have you know some
CPU test tool for this CPU.

I try, for now, memtest86+ 1.1 (prebuild fd image from
www.memetest.org) and system passed all tests. (RAM and cache are OK)

I try install Windows XP (32-bit) and they also work fine.


Comment 6 Sahil Verma 2004-03-29 19:31:09 UTC
memtest may not always trigger the fault. Try XP 64-bit beta or
FreeBSD amd64.

Comment 7 kg4zmp@ardmore.net 2004-04-25 02:49:03 UTC
It's not a hardware problem.  I get the same error when trying to
install Fedora 64.  Windows XP 64 Beta installs with no problems.  I
have run the AMD CPU test software (amdcpuid.exe and cpuinfo.exe) and
it finds no errors with my AMD 64 3200+ CPU.  I think there is a bug
somewhere in the installer.

Comment 8 kg4zmp@ardmore.net 2004-04-27 02:43:05 UTC
I have now installed Windows XP 64 Beta and Mandrake 10.0 AMD64 Beta
successfully.  The issue with Fedora Core x86_64 on an MAD64 system is
not a hardware issue - it is a software issue, a bug in the installer.


Comment 9 kg4zmp@ardmore.net 2004-04-27 02:43:55 UTC
danged typos... an AMD64 system not a MAD64 system

Comment 10 Tomas Dobrovolny 2004-05-24 19:35:31 UTC
I have changed the CPU and all is OK. This was CPU bug.
