From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) 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. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot from installation CD Actual Results: Kernel panic Additional info: System configuration MB: MSI Neo8-FISR (Chipset: Via K8T800, Via VT8237 South bridge; on board: Via VT8237 SATA - disabled in bios, Promise 20378 at SATA mode, Realtek 10/100/1000 NIC [8110S], Realtek ALC655 audio , Via 6370 IEEE 1394) CPU: AMD Athlon64 3200+ RAM: one 512MB DDRAM; 450MHz; 2.5CL VGA: ATI Radeon 9800 Pro Video: MSI TV@anywhere master(CX23881) CD/DVD: Nec 2500A CD-RW,DVD-RW on second ATA chanel of VT8237A HDD: ATA WDC400JB as boot disk on VT8237; SATA WD1200JD on Promise 20378 SATA Mouse: Microsoft wireless optical mouse 2.0 on USB

Looks like bad hardware, specifically the CPU. Something in the higher oreder bits of the registers (?), since i386 kernel works.
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.
memtest may not always trigger the fault. Try XP 64-bit beta or FreeBSD amd64.
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.
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.
danged typos... an AMD64 system not a MAD64 system
I have changed the CPU and all is OK. This was CPU bug.
