ATA failure and interrupt storm on sk0

[Johan Pettersson]

CVSuped latest -CURRENT today and installed. When booting the new kernel I got this...

ad4: FAILURE - already active DMA on this device
ad4: setting up DMA failed
ad4: TIMEOUT - READ_DMA retrying (2 retries left) LBA=4831423

then it wants me to mount / manually. Setting hint.apic.0.disabled to 1 at the boot prompt helps but after running a while I get that messages again and the taskqueue is stalled and I must reset the computer. Also when hint.apic.0.disabled is set to 1 I get this...
