Hi,

I've switched recently to new xorg and kms driver. Sometimes after booting my
system (9.1-STABLE #0 r245741 amd64) shows high load:

interrupt                          total       rate
irq1: atkbd0                         612          0
irq9: acpi0                         3693          1
irq12: psm0                         7512          2
irq16: uhci0 uhci3             377172955     144069
irq20: hpet0                     2923357       1116
irq23: uhci1 ehci1                 47432         18
irq256: hdac0                      80799         30
irq257: alc0                       78474         29
irq258: iwn0                       19994          7
irq259: ahci0                     100016         38
irq260: vgapci0                    31250         11
Total                          380466094     145327

I've never seen this with old xorg. The problem is not always reproducible, 
but it's enough just to load i915kms module without staring X to trigger it.

Any idea?

Thanks,
Max
