Do you see the strange behavior if you boot with ACPI disabled?

Hi there, got it installed :-)

I don't know why I went to check vmstat -i, but when I did I got a bit of strangeness.

What's with all the strange stray's? Is this normal? It doesn't seem to be affecting much but then it doesn't look quite right either. Where's my fxp0 card too! Is this perhaps an ACPI issue? All I can think of sending you at the minute is a dmesg, would you like to see anything else or is it a harmless ignorable problem? I know I didn't get anything like this with 5.x for what it's worth.

I'm now cvsupping stable, so I'll let you know if it's the same with stable tomorrow most likely ( I have to sleep some time :) )

Unfortuantly I can't really try booting with ACPI disabled right now as I am doing a buildworld. I will try as soon as it finishes (before installing it all) and let you know if it goes away though. Do you think it could be related to ACPI?

Everything appears to be running good though.

>>mux irq11 42624 13

Would this be my fxp card maybe? top seems to be always showing 0.0% interrupt usage.
