Not sure what the difference is between the DL360 and the DL380, but
here's my take anyway.
I have two DL360s running 4.8-RC2. This is the RC2 from the ISO. I
haven't sup'ed it yet. They both run fine with SMP enabled. Neither of
them have any problems with the bge either.
Your mention of the interupts made me think of this. It's written for
Linux, but it (probably?) still applies. I have the BIOS set the way
described below. I found this on HP's site somewhere ...
------------------------------------------------------------------
Tip: Red Hat Linux 8.0 does not recognize a single hyper-threading
enabled processor as an smp capable machine. As a result, the uni-processor
kernel is installed when RBSU is configured as follows:
OS = Linux
MPS = Auto
HT = Enabled
After Red Hat installation is complete, install the smp kernel RPM
from the Red Hat Linux 8.0 CD #1. After installing the smp kernel, open
the /etc/grub.conf file and find the smp kernel entry. Edit this entry
to make it the default.
HP recommends the following RBSU configuration in this case:
OS = Linux
MPS = Full Table Mapped (if shared interrupts are desired) OR
Full Table (if shared interrupts are not desired)
------------------------------------------------------------------
I forget the technical reason for this. Something about the BIOS and
mapping interrupts (ask google). And I'm not saying that this will fix
your problem. Only that I have 2 DL360s w/2x2.8GHz Zeons and 1G of RAM
running on this setup, happy as you please.
HTH
