This is what gets written to the console when trying to boot this kernel.
Non-smp kernel fails identically. Kernel 2.6.13-1.1532smp has no problems.
I see the same. 2.6.13-1.1532* works fine. I'd be happy to give more details
about my system if you tell me what you need, here is what I can think of:
AMD Athlon(tm) 64 X2 Dual Core Processor 4200+
latest version of the BIOS (as of today)
I'll attach $(lspci) and $(dmesg) on the system when running 2.6.13-1.1532smp

Latest kernel (2.6.14-1.1644smp) plus changes to BIOS settings fixes this.
