Hi all,

Firstly, apologies for the length of this. It's my first mailing list posting, so I hope I'm not breaching any etiquette codes. Also I've only been using FreeBSD for a couple of years, so I'm still very new to the system.

I have recently become the proud owner of a second-hand HP NetServer e800, which has two Pentium-III class [686] CPUs in it. I've installed 6.2-RELEASE-p3 [which is also referred to as 6.2-STABLE, is that correct?] and built myself a SMP kernel. I'm sure it's a SMP kernel, because the config file has "options SMP" in it and while running it "sysctl kern.smp.maxcpus" returns 16. The BIOS says there are two CPUs, so I guess the second CPU is in fine condition and ready to go.

I've done a little Googling and digging around in the system. First, the obligatory "uname -a" output:

"FreeBSD 6.2-RELEASE-p3 FreeBSD 6.2-RELEASE-p3 #0: Tue Apr 17 15:01:06 BST 2007 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GAKKO i386"

There's nothing in /var/log/messages about CPUs, as far as I can tell.

The output of "dmesg" provides a possible clue:

"real memory  = 268369920 (255 MB)
avail memory = 257167360 (245 MB)

Does the dmesg output start with the memory stats?  I'd expect
MPTable:, Timecounter,  and CPU: lines above your quoted material.

Definitely have BIOS/OS issues, though.  As Chuck suggests, play
around with the PnP settings in your BIOS setup, possibly update....

I've got a box similar to yours, I *think*; unfortunately, it's
be on a distant job site for over two years (originally running
5.3-RELEASE with SMP on two Pentium-III Lancewood chips), and it's
been so long since I was in the BIOS on that box I've no idea what
the settings are.

Several possible clues in that snippet, now that I look at it. The "MADT" line is suspicious but I think the real culprit might be revealed in the "can't fetch resources" line. On the other hand it might be a completely unrelated problem. Google is silent on the subject of "AE_AML_INVALID_RESOURCE_TYPE", and I don't see it in the Lehey or Lucas books.

Finally, mptable shows what's really going on:
"MP Config Base Table Entries:
Processors: APIC ID Version State        Family Model Step Flags
             3       0x11    BSP, usable  6      8     3    0x387fbff
             0       0x11    AP, unusable 6      8     3    0x387fbff"

Apparently the "application processor" is "unusable", whatever that means. I am now stuck.
