--MP Bios bug 8254 :timer not connected to IO-APIC


I installed federo8 on my PC.installation is done,but while booting i get this error and PC hangs while entering user name and password

--MP Bios bug 8254 :timer not connected to IO-APIC

Most of forums suggested to pass this "acpi=off noapic" parameter to kernel.But when i pass it ,i got the fallowing error

Bios bug no explicit IRQ entries using default mptables.(contact vendor)

Please suggest some possible solutions.
