Hello.
We have been running FreeBSD 4.6-5.1 systems for 1.5 years and are being
plagued by these:
Dec 18 15:15:39 <> /kernel: ad0: WRITE command timeout tag=0 serv=0 -
resetting
Dec 19 15:03:23 <> /kernel: ad0: READ command timeout tag=0 serv=0 -
resetting
In our rack we have 34 identical drives (IBM IC35L080AVVA07).
24 drives on Windows 2000 : no problems.
4 drives on Linux 2.4.x : no problems.
2 drives on RELENG_4_8
(VIA 82C686, VIA C3) : no problems
4 drives on RELENG_4_8
(nVIDIA nForce, XP 2000+) : r/w timeouts, fs corruption.
(1 drive/system, 6 FreeBSD boxes)
The good systems have been running the 1.5 years without a hitch. The
four identical RELENG_4_8 systems have all had corrupted filesystems (at
least once every two months).
We have tried the following:
- Changed ATA100 cables (3 diff. types, all 80-wire)
- Disabled DMA (use PIO4) (hw.ata.ata_dma="0" in loader.conf)
- Disabled DMA in BIOS setup
- Changed motherboard (MSI MS6734, VIA KM400, vt8235 ATA)
- Changed power supply (added 100W)
- RELENG_5_1.
None of these changes has helped. The only change seen when disabling
DMA is additional messages: "timeout waiting for DRQ - resetting".
I have searched the net for more information on this topic for over a
year, and all I find is replies like:
- "Just change the cable, dude.." (did that, still timeouts)
- "IBM drives are bad for you." (seen this with other drives too)
(drives work well on Linux/W2k)
- "Disabling DMA fixes it." (tried that, it didn't)
- "ATA is for wimps. SCSI rulezz." (different discussion)

dmesg, pciconf and kernel config are attached. No special compilation
options (except -DIPFW2) are used. I can provide more information on
request.
We're now running FreeBSD 4.8-RELEASE-p14 and FreeBSD 5.1-RELEASE-p8,
but the problem has been around since we started out with 4.6 I
believe. The "good" and "bad" FreeBSD systems all use the same
kernel/world.
The reason why we have used such low-end hardware in these boxes is that
they are part of a highly redundant cluster solution for crypto
processing (no storage is used for application purposes). This means the
system can cope with the occasional fs corruption, but we would still
prefer to get rid of it.
I know this problem has been discussed before, but wanted to add more
data to the discussion. I don't think all of the reports should be
attributed to bad HW. Nevertheless, even if the hardware is broken, the
system should preferably function equally well/bad as with Linux/W2k.
Any help is greatly appreciated.
Best Regards,
Oivind H. Danielsen
