freebsd stable - Mar 2006 - "TIMEOUT - WRITE_DMA" with SiI 3512 SATA on IBM eServer 326

Hi,

I have a problem, probably with the SiI 3512 SATA150 controller in a
dual-Opteron IBM eServer 326:

Every once a while the kernel issues a message like:

  ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=150190687

The system waits a few seconds and continues to work normally.

It typically occurs several times a day most likely depending on the
load of the (SATA connected) hard drive.

We have two machines of the same hardware configuration, both with two
hard drives (identical type). The problem is the same with all the 4
drives on both machines. Thus I assume it's more a driver problem than
a bad SATA cable.


We are currently using one of the machines with FreeBSD 5-stable
(RELENG_5) and the other with some Linux. While Linux didn't have a
problem with the hardware, FreeBSD did. We tried 5.4-Release and
6.0-Release both with i386 as well as with amd64. We found that only
5.4-Release on amd64 was able to install, even though with some
warning. The other versions failed to install at all.

After successful installation we noticed two problems:

 - After a couple of uptime hours top stopped to report CPU
 utilization numbers (all 0). This went away by changing the
 timercounter hardware from ACPI-fast to i8254
 (kern.timecounter.hardware=i8254 in /etc/sysctl.conf).

 - The "TIMEOUT - WRITE_DMA" messages occur from time to time, always
 stopping the system for a few seconds (probably all processes trying
 to access the hard drive).

So far I didn't manage to solve the latter.

I upgraded to 5-stable (RELENG_5) with cvsup (last time today) but the
problem is still the same.

Besides the occasional hickups the machine runs fine.

The SATA controller reports as "SiI 3512A SATALink BIOS Version
4.3.47" during BIOS startup.

I'll attach the last dmesg output.


Any suggestions?


Best regards, Martin
