Ubuntu 14.04.5 i386
Ubuntu 16.04.2 i386
I have a small DIY server for long time and I used PCI card with chip "SiL 3112" to connect SATA drives, to have RAID volume; I use SW RAID (mdadm). I am sure that when I built this system long time ago, it worked fine but it reports many DMA errors now, too many errors and it works slowly because there are many retries. I changed all my SATA cables, etc but that was not a source of the trouble. Real trouble is chip SiL3112. I believe that some change in Linux kernel module sata_sil started the trouble. I cannot tell when it happened, 2017, 2016 or even 2015?
Anyway, I replaced my SATA card with card based on SiL 3114 and it works fine!
$ lspci | grep 3114
00:0d.0 Mass storage controller: Silicon Image, Inc. SiI 3114 [SATALink/SATARaid] Serial ATA Controller (rev 02)
I see this message in dmesg output (14.04.5, 3.13.0-117-generic #164-Ubuntu SMP Fri Apr 7 11:06:36 UTC 2017 i686):
[ 3.543370] sata_sil 0000:00:0d.0: version 2.4
[ 3.544339] sata_sil 0000:00:0d.0: Applying R_ERR on DMA activate FIS errata fix
Could be the same "workarround" applied to SiL 3112 card? I know that when SiL 3112 is in my PC, I cannot find any message "Applying R_ERR on DMA activate FIS errata fix" in dmesg output.
BTW, I have found some comments on the net, that these cards are "broken" and should be avoided as plague, etc. Well, I think that my SiL 3112 worked fine in the past and SiL 3114 works fine just now, so it is driver problem (and some HW design bug, so the performance of chips is limited by this SW workaround).
This report is from Ubuntu 14.04.4 but I already tried 16.04.2 but it was not better, DMA errors were there but were more visible (annoying).
I can update this report with details about SiL 3112 card but it is out of my PC now...
SATA card with SiL 3112 is loaded with Non-RAID BIOS v 4.2.84.
