Folks, Here's a brief rundown regarding 4.8-R on the Supermicro X5DP8-G2 motherboard. Dual 2.4 533FSB Xeons and Kingston ValueRAM memory, and Seagate U320 disks. First, I ran into problems with my memory and motherboard...these problems were fixed after RMAing the board to supermicro. My curse strikes again. :) Firmware on my Seagate disks needed to be updated to 0006. Supermicro provided the firmware, a list member provided source for a freebsd-operable firmware update program. Some information is available here: http://www.seagate.com/support/disc/u320_firmware.html As a uniprocessor board, the system had no issues with a GENERIC kernel. Enabling SMP WITHOUT Hyperthreading enabled in the kernel or Bios resulted in errors and hangs along these lines: >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< ahd0: Dumping Card State at program address 0x10f Mode 0x33 Card was paused WITH hyperthreading enabled in the kernel or bios, the system worked perfectly, completely stable so far. A list member suggested that the no-HTT problem is because the boards BIOS leaves the local APIC on the logical CPUs enabled, which breaks the way FreeBSD handles things. He provided a patch for 4.8-R that always enables HTT, but disables the local processors, similar to the way this is handled in 5.x. With this patch in place the system has 2 CPUs (0,2) and is 100% stable so far. I'd like to see Supermicro address the APCI issue, but outside of that they've been very helpful both before and after the sale. (I ask a lot of questions...:) I'm now 100% happy with this system, and motherboard. Thanks to everyone for your help getting this guy going. I've only been running it for a few days now, but so far no other quirks that I've found. I've not used the 1000Base interfaces yet, but since they're a recent intel chip, I'm sure they'll be fine. At 100Base they seem fine, at least. :) I'd recommend this motherboard, and/or chassis. ...david --- david raistrick drais@atlasta.net http://www.expita.com/nomime.html
