I have noticed some strange behavior on 6.2-RC1 with a IBM x336 server here. It never crashed but the throughput felt off, so I disabled Hyper-threading and things seemed to perform the way I expected it to should. I would have more details when I actually have time to work on the server itself, however in the meantime give it a shot. If you have 2 CPU's you shouldn't see the CPU2/CPU3 listed just the 2 aftewards. FYI - I have used that particular controller successfully on several servers recently so I don't think that should be a overall issue for you.

Re: 6.1 Freezes - Suspect SCSI Issue
I also have had the EXACT same problem. I have suspected the SCSI system as well. I have played with all the hardware settings IE transfer rate etc to no avail. I am not willing to disable the SMP, as this is my workstation, and I need the extra speed. === FreeBSD 6.1-RELEASE-p10 #2 cpu0: ACPI CPU on acpi0 cpu1: ACPI CPU on acpi0 pcib0: ACPI Host-PCI bridge on acpi0 pci0: ACPI PCI bus on pcib0 pcib1: ACPI PCI-PCI bridge at device 2.0 on pci0 pci1: ACPI PCI bus on pcib1 ahc0: Adaptec aic7880 Ultra SCSI adapter port 0xfc00-0xfcff mem 0xfcfff000-0xfcff irq 30 at device 6.0 on pci1 ahc0: [GIANT-LOCKED] aic7880: Ultra Single Channel A, SCSI Id=7, 16/253 SCBs aac0: Dell PERC 2/Si mem 0xf400-0xf7ff irq 31 at device 2.1 on pci0 aac0: [FAST] aac0: Adaptec Raid Controller 2.0.0-1 Why/what is the [GIANT-LOCKED]?

FYI - I have used that particular controller successfully on several servers recently so I don't think that should be a overall issue for you. In my case the controller is slightly different (29320), but I think the driver is the problem. It used to work flawlessly as long as I run 5.x, but started freezing as soon as I upgraded to 6.1.

The solution was to turn SMP off, unfortunately :( I don't think I'm ready to turn SMP off just yet. Are these Xeon's? If so you might want to try disabling Hyper-threading .. but I'll try disabling Hyper-threating. And yes they are Xeon's, the Nocona version. No. In my case one is an Athlon64 and the other an Opteron. FYI - I have used that particular controller successfully on several servers recently so I don't think that should be a overall issue for you. Thank you for your vote of confidence on this. I really think this is a drive issue or a drive/drive compatibility issue due to the weird results I'm getting on camcontrol tags command. BTW camcontrol defects shows 0 defects. In my case the controller is slightly different (29320), but I think the driver is the problem. I'm running a 29160 on a 4.9FB (dual Xeon) machine and it has been rock solid for 1.5years. It used to work flawlessly as long as I run 5.x, but started freezing as soon as I upgraded to 6.1. Notice, however, that I don't have data to support my thesis yet. bye av.
