Anyhow, my understanding is that the current work-around to this
problem is to turn DMA off for your ata drives. I guess this can be
done manually with the atacontrol command as I've been doing (though
as you'll see in my message linked above, I apparently need to do it
differently/sooner). I also understand that you can do so by setting
hw.ata.ata_dma=0 in /boot/loader.conf .
Yes, I saw this suggestion in other posts, too. Well, I gave it a try.
I disabled dma yesterday and today I got the following:
Timecounter TSC frequency 498669235 Hz quality 800
ad0: 8693MB IBM-DJNA-370910/J74OA30K [17662/16/63] at ata0-master PIO4
ad0: TIMEOUT - WRITE_MUL retrying (2 retries left) LBA=1573151
ad0: FAILURE - WRITE_MUL timed out
That's something completely new. Does anyone know what that means?
Like the symptoms you got with DMA enabled, it *probably* means you
have *some* kind of hardware problem. The cable would be a likely
candidate, but I'd definitely be making extra backups if I were you.
