I have a machine that was running Windows XP until I recently
installed 2.2.2 on it.  This was mainly for the purpose of trying out
Hammer.  It contains a 40GB drive, which I made the boot drive and
installed with Hammer.  The other 2 drives are a 300GB Samsung IDE and
a 200GB Western Digital IDE, both connected to a SiI 0680 controller.
I've succcessfully installed Hammer on the WD drive, but the Samsung
fails as follows:

# newfs_hammer -L BACKUP /dev/ad6s1a

I ran a Samsung diagnostic on it and it found a DMA command timeout
problem (service code AJ27), so it appears that the drive really does
have a problem.  Just for kicks though, I tried installing UFS on this
drive and it gave me no complaints and seems to actually work.  Also,
Windows XP seemed to be working fine with this drive.  Does that make
any sense?

I don't see your Silicon Image HBA reported in dmesg all that differently from one I am using.

Relevant ID's from FreeBSD 7.1 AMD64 are;

atapci0: <SiI SiI 3114 SATA150 controller> port 0x40a0-0x40a7,0x4094-0x4097,0x4098-0x409f,0x4090-0x4093,0x4080-0x408f
mem 0xdc040000-0xdc0403ff irq 19 at device 6.0 on pci10

Yours form DragonFly were:

atapci0: <SiI 0680 UDMA133 controller> port
0xec70-0xec7f,0xec90-0xec93,0xec98-0xec9f,0xeca8-0xecab,0xecb0-0xecb7
mem 0xff1afc00-0xff1afcff irq 11 at device 11.0 on pci2

Further - I've had chronic trouble of the same sort with WD, Maxtor, Fujitsu, and Samsung drives on the Intel IHC7 (Tyan Tomcat) under FreeBSD between 6.2 and 7.1 - not entirely absent on 7.1, either, and have moved drives OFF the onboard IHC7 onto a cheap-as-dirt SiI PCIB HBA that runs 'em slower, but trouble free.

Mine has:

atapci1: <Intel ICH7 SATA300 controller> port 0x30c0-0x30c7,0x30b4-0x30b7,0x30b8-0x30bf,0x30b0-0x30b3,0x30a0-0x30af mem 0xdc500400-0xdc5007ff irq 19 at device 31.2 on pci0


You are showing an IHC2:

atapci1: <Intel ICH2 UDMA100 controller> port
0xffa0-0xffaf,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 31.1 on
pci0

(rest of dmesg snipped).


So I don't think it is the drives, and it may not be DragonFly, either.

Intels' IHC series are as ubiquitous as housefly feces - and not a great deal more welcome in our house these days as drive controllers go.

HTH,

Thanks, Bill.  I tried switching the drive ports on the Sil 0680 and no luck. I have an open IDE port on IC2, so I tried moving the problem Samsung drive there and, voila, it works fine with Hammer now.  The WD drive is still working fine on the Sil 0680, so I'm leaving it there.  I can only conclude at this point that the Sil and the Samsung simply can't talk DMA, for whatever reason, and I'm not inclined to chase it down.  I read somewhere that if Windows XP has problems getting DMA to work, it automatically switches to PIO.  Could that be why XP was OK with the original configuration?
