is this an 11.31 feature? cpu sequence...

we got our first Itanium server, and was wondering if the cpu sequence listed below is normal?


rx8640, running 11.31


Code:

I opened a case w/HP and they gave me some math formula which explains the cpu sequence jumps.
So I guess I'm looking for a confirmation that support isn't reaching :P

another interesting item, are these fab_cpu_hwpath messages found in dmesg:

Wouldn't it be great if I could resolve any issues before the box becomes production?

thanks,

It looks to me like each cell can support 16 cpu's. If not today, then someday. Gaps like this are common and they usually indicate missing cpu's. I wouldn't worry about it.
