SiS 964 shows up as UDMA133, connected SATA150 drive shows as UDMA33 - FreeBSD 8.0

Just upgraded to FreeBSD 8.0 STABLE using the steps at: http://people.freebsd.org/~rse/upgrade/

There's one SATA HDD in the box, and now it's showing up as being restricted to UDMA33. dmesg output is below.

Generic kernel (despite the config name shown in the dmesg output -- unchanged config).

It's been a while since the box was upgraded. Started with FreeBSD 6.2, went to 7.3, then to 8.0. Under 6.2, the drive reported SATA150. Didn't check under 7.3. (Drive was installed into the machine but not mounted as anything yet.)

Google isn't helping me yet. Found this:
http://markmail.org/message/qvmegcwgmtos5ctj

But my throughput speeds reported by diskinfo are much lower, so I'm not yet ready to accept the "don't worry about it" answer.

atacontrol says "SATA150" isn't a valid mode. It also says the disk is SATA revision 2.x:
Code: 
ATA channel 2:
    Master:  ad4 <WDC WD15EADS-00P8B0/01.00A01> SATA revision 2.x
    Slave:       no device present

dmesg (controller is atapci1, drive is ata4):

Motherboard is ECS 761GX-M754. No BIOS updates available.

pciconf reports "Raid Controller(?Mode Raid1)", and yet the BIOS config is not set to any RAID option.

If I'm reading ata-pci.h correctly, atapci1 is ATA_SIS181 according to pciconf (#define references chip ID?) and yet dmesg says it's SiS 964. ata-sis.c, of course has ATA_SIS181 set to ATA_SA150 and ATA_SIS964 to ATA_UDMA6.
 
Seems odd that the LPC bridge (isab0) reports 0x09641039. The only definition I can see for that in the kernel is ATA_SIS964.

I see that atapci0 is also reported by dmesg as the exact same device type (SiS 964), and yet its chip ID from pciconf is 0x55131039 -- ATA_SIS5513.
 
Any differences in # dmesg output if you directly boot from 8.0-RELEASE install media? If not, are there differences when you unplug all disks except the SATA one? You may also try 9.0-CURRENT for testing. Can you swap the SATA cable?
 
Thanks - I'll try booting from the install media and attaching a jumper this weekend, and maybe another SATA cable.

Trying 9.0-CURRENT is a bit more than I can take on right now. :)
 
This is a probably driver error. And probably it is just cosmetic.

PM2 jumper is not related to connection speed. PM2 in WD terms means same as PUIS (Power Up In Stand-by) in ATA specification. It is one of methods for implementing staggered spin-up for ATA devices.
 
Thanks. With the suggesting that it's cosmetic, I went ahead and started using the drive ZFS isn't complaining. Didn't have time on the weekend to try jumpers or 8.0-RELEASE, so I'm going to go with mav's suspicion that it's cosmetic and assume that to be the case for now.

Even if it's affecting speed (which it doesn't *seem* to), that's ok. Mostly serving up files over an internet connection, 802.11g and 100Mbps Ethernet... and it seems plenty fast enough for that.
