I also have both machines running nicely. The only expected panics are of a static nature during boot when the kernel discovers its missing a necessary APIC connection. No one has reported random panics (knock on silicon) yet. --- > The newer kernels also feel somewhat more responsive under load, > though as yet I don't have any quantitive data to back this > assertion up. I had the same feeling of improvement but figured it was just wishful thinking on my part. Thanx for the report. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
