10-30 minutes later, it finally gets through the boot.
/etc/fstab:
/dev/ad2s1 /X ufs rw 2 2
the problem here is the device needs to be PIO4
$ atacontrol mode ad2 PIO4
current mode = PIO4
My problem is how do I get this to persist across reboot ?
Have a look at man 4 ata
Your answer is probably:
hw.ata.ata_dma=0
in /boot/loader.conf
Are you sure it is not a faulty (or failing) disk though? This size /
age drive should have no problem running in DMA mode.
