Description of problem:
Fedora Core 5 refuses to boot

Version-Release number of selected component (if applicable):
kernel 2.6.15-1.2054_FC5 ( i386 )


How reproducible:
100%

Steps to Reproduce:
1. Start my Computer, and try to boot into FC5
  
Actual results:
I get an error screen that looks something like this ( its different each time )
cpu : 0
eip : 0060:[<c0165fb7>] not tainted VLI
eflags : 00210202
eip is at d_albc+0x151/0x1bc
eax:f68195b8 ebx:f797cdd0 ecx:00200246
edx:f6ef201b esi:f6ef201b edi:eefe43e1

process : python ( pid:1547, threadinfo:f797c00 )

It also gives me some call trace.
It also says it will continue in 120 seconds.

After 120 seconds, sometimes i again get a similar screen, or my comp just 
stops responding.

error screen #2
cpu 0
eip 0060:[<c0165fb7>] not tainted vli
eflags 00210202
eip is at d_alloc+0x151/0x1bc

edx:f7fb06c0   esi:f6a9d00a   edi:ee6e43e1

process cpuspeed ( pid: 1147, threadinfo=f6f9b000 task f6f2e550 )


Expected results:
Normal Boot

Additional info:
The error screens are different each time i boot.
I also tried booting into runlevel 1, 2 & 3, with same results
