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? Thanks in advance Richard Puga Here is the info from dmesg and atacontrol; kernel: ad3: TIMEOUT - READ_DMA retrying (1 retry left) LBA=0 kernel: ad2: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=324524575 kernel: ad2: TIMEOUT - READ_DMA retrying (1 retry left) LBA=3780487 kernel: ad2: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2651511 and so on.... atapci1: <Intel ICH5 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x14a0-0x14af at device 31.1 on pci0 ad4: 476940MB <Hitachi HDT725050VLA360 V56OA73A> at ata2-master SATA150 ad6: 476940MB <Hitachi HDT725050VLA360 V56OA73A> at ata3-master SATA150 atacontrol cap ad4 Protocol Serial ATA II device model Hitachi HDT725050VLA360 serial number VFD400R40E0EHC firmware revision V56OA73A cylinders 16383 heads 16 sectors/track 63 lba supported 268435455 sectors lba48 supported 976773168 sectors dma supported overlap not supported Feature Support Enable Value Vendor write cache yes yes read ahead yes yes Native Command Queuing (NCQ) yes - 31/0x1F Tagged Command Queuing (TCQ) no no 31/0x1F SMART yes no microcode download yes yes security yes no power management yes yes advanced power management yes no 0/0x00 automatic acoustic management yes no 254/0xFE 128/0x80

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..

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
