Stops Linux from complaining: [0.097286] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=0 pin2=0 [0.100005] ..MP-BIOS bug: 8254 timer not connected to IO-APIC [0.100005] ...trying to set up timer (IRQ0) through the 8259A ... [0.100005] ..... (found apic 0 pin 0) ... [0.143507] ....... works. Change-Id: Ic09a6940f80e3da2c1f3c0ef04fb50a4096b7943 Signed-off-by: Jonathan A.
