Hi all,

I wonder if somebody has some directions for me.
I added a 40GB hd and while doing newfs on a partition I get a couple of:
ad3: WRITE command timeout tag=0 serv=0 - resetting
ata1: resetting devices .. done
and then:
ad3: trying fallback to PIO mode
ata1: resetting device .. done
ad3: timeout waiting for DRQ - resetting
configure disks in PIO mode? Perhaps you have buggy chipset for DMA modes?
