      After setting up squid using a SATA 300MB/s 2.5" hard disk on an D945GSEJT I seem to be getting these errors which eventually lead to a kernel panic. I have tried switching off AHCI and using IDE mode but the errors continue. One strange thing is that pFsense seems to detect the SATA controller as a SATA 150 even though the intel spec page claims its 300:

      atapci1: <intel ich7m="" sata150="" controller="">port 0xf0e0-0xf0e7,0xf0d0-0xf0d3,0xf0c0-0xf0c7,0xf0b0-0xf0b3,0xf0a0-0xf0af mem 0xdff40000-0xdff403ff irq 19 at device 31.2 on pci0</intel>

        Appears there is a fix here: http://linux-bsd-sharing.blogspot.co.uk/2009/03/howto-fix-sata-dma-timeout-issues-on.html but it looks like this means patching the kernel is this even possible with the files shipped with pfsense?

          What version of pfSense are you using? You might get better results using a pfSense with a more up to date version of FreeBSD.

            I was using 2.0.1 release, but I tested with 2.1 dev and its the same. Apparently the ata subsystem has been updated for FreeBSD 9, but that's a while off for pfsense i think :(

              You could try to disable DMA maybe (check the wiki) but usually those sorts of timeouts are more a sign of a disk/controller problem. Drivers are possible, but less likely, especially if it happens on multiple versions. Check Diag > SMART Status and run a report on the drive and see if it shows any errors (post the output here and we can look it over)

                Unfortunately I don’t have the disk in my system anymore. I did check the smart logs and run a full smart test, none of the errors matched any time of the write dma errors. The disk was working fine in a laptop & the motherboard was working correctly using windows 2008 with another disk. I may give it another go sometime, I was using it as a squid disk I will update if I do.

                  Using this disk again. Errors popping up again on a fresh install. Have disabled DMA getting this at boot will see if it continues:
