Oh, ehm, DMA seems to be enabled all the time. False alarm.

[ 22.057440] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 22.057569] USB Universal Host Controller Interface driver v3.0

[ 22.253784] ata1.00: configured for UDMA/133
[ 22.457188] ata2: SATA link down 1.5 Gbps (SStatus 0 SControl 300)
[ 22.469100] scsi 0:0:0:0: Direct-Access ATA WDC WD5000ABPS-0 02.0 PQ: 0 ANSI: 5

Now i'm wondering why the CPU iowait goes up to 80% when i copy some files around the disk... does anybody know why?

Thanks, Sannny
