I'm seeing errors on a new port multiplier install.
The mobo has a J-Micron SATA controller: JMicron Technologies, Inc. JMicron 20360/20363 AHCI Controller (rev 03)
The port multiplier has a SIL 3726 chipset. AFAICT, this is a supported comnbination. The kernel recognizes the chipset.
The system has an adaptec SCSI controller w/ 2 15K SCSI drives, 6 internal SATA drives, and 3 external SATA drives using the port multiplier. Because of a broken bios (ARGH!) I have to power up the external drives after the system scans the SCSI bus. This seems to cause no problems. Here's a log of a recent boot (scroll down for the error I see after the system is booted):

Once the system is up and running, I get these errors. They appear anywhere from several hours to a few minutes apart. What exactly does this mean? It doesn't seem to have any impact on the performance of the drives. Typically, these drives are very heavily loaded; I've been dumping > 1TB of data to them while rebuilding the RAID-5 array, so they're pretty well maxed out.
