I needed to disable ACPI too. I'd generally like to leave it on for the temperature monitoring, but you do what you can. I looked at the DSDT briefly and think there was a potential ordering issue between the floppy disk drive and the keyboard resources ... the init method for the floppy twiddles an enable bit the other ISA/LPC devices all look at when building _CRS. Since we decided to not buy any more IBMs (due to QA issues... don't seem to understand how to jumper ATA drives) I haven't looked at it any further. > b.

The x345 didn't look like a different mainboard. You are in a twisty maze of IBM part and config numbers, all different... :) > c.

Sounds like your workload is one of those that isn't HT-happy, unless you mean general operation. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
