Using powertop I also notice that after this my power consumption shoots sky
high after this error. Instead of the normal 11-14W I get:

----------------
Power usage (ACPI estimate): 28.0W (0.8 hours)


Top causes for wakeups:
  99.8% (86410.4)       <interrupt> : ahci, yenta, i...@pci:0000:00:02.0
  0.1% ( 97.3)       <interrupt> : PS/2 keyboard/mouse/touchpad

---------

and this is on the IRQ that was just disabled:
 16:  149416472       8450   IO-APIC-fasteoi   ahci, yenta,
i...@pci:0000:00:02.0

I am not familiar with how this all works (i.e. what disabling an interrupt
might lead to), so sorry I am mentioning something very obvious.

Niel
