Ad4: TIMEOUT - WRITE_DMA retrying (1 retry left)
-
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:
