Description of problem:
Major performance issues ~10mins from grub screen to autologin! at which point the gui (kde4) is unusable, studying dmesg some things jump out at my untrained eye.
1. ACPI Error (tbfadt-0453): 32/64X address mismatch in "Pm2ControlBlock": [00008800] [0000000000008100], using 64X [20080609]
2. MP-BIOS bug: 8254 timer not connected to IO-APIC
3. mtrr: base(0xc10b0000) is not aligned on a size(0x640000) boundary
4. APIC error on CPU0: 00(40)

Can you get /proc/mtrr from an older release (that works at normal speed?)
Comment 7 Chuck Ebbert 2008-11-10 22:09:29 EST
Can you try adding:
