I am working with a new IBM XSeries 226 server. It worked fine with the original 80 gig drives. Upon replacing them with 2 new Hitichi 500 gig drives I get DMA timouts at random times while using the on board Intel SATA controller. I put a Promice SATA controller in the machine and everything works great. Has anyone heard of a problem with Intel controllers?

They're attached to a different PCI device. UDMA100 is the ATA/IDE port (read: old PATA), not an SATA port. What you should be pointing to is something that looks like this: atapci0: <Intel ICH5 SATA150 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xf000-0xf00f irq 18 at device 31.2 on pci0 (The above example is from a machine we have sitting around doing heavy I/O work due to MySQL. We have no disk problems there.) Now... I have seen similar behaviour to what you've described on an Intel-based SATA controller (ICH6) with a Western Digital drive that I have personally used and determined to be reliable on Windows and verified as such with WD's testing software under DOS too. I've only seen this happen *once* on the system.

There were some recent ones regarding DMA, but I believe they were for ATAPI devices and not ATA (disk) devices. http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ Note my system kernel is from March 8th. Since then, there's been a lot of changes regarding DMA, including some "oops I broke this" fixes which may explain what I am seeing, and maybe what you are too. Though this is in regards to 64-bit DMA, and I believe most of my systems (and yours?) are using 48-bit DMA. http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ata-dma.c Soren might know what's going on here though... -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Thank you Jeremy for your reply, Sorry I didnt incluce my version of FreeBSD, its been so long since I posted to the lists I forgot to tack on a complete copy of my dmesg.. pele /root 126% uname -a FreeBSD pele 6.1-RELEASE FreeBSD 6.1-RELEASE #1: Thu May 10 23:06:18 HST 2007 root@pele:/usr/src/sys/i386/compile/PELE i386 The only thing I added to the stock GENERIC kernel is atapicam. I have been beating on both hard drives while connected to the Promise controller. I will load FreeBSD 6.2 and see if that solves the problem else I will deliver it with the Promise controller. I will be building another one just like this soon and will test -stable on it. Thanks again for your help Richard Puga puga@mauibuilt.com Copyright (c) 1992-2006 The FreeBSD Project.
