index | next in thread | raw e-mail
A few weeks ago a friend was moving and gave me an
ALR "Revolution Q-SMP" EISA-based server. It's got
two 90MHz P5 CPUs, but I'll be darned if I can get an
SMP kernel to boot. The generic kernel and any
uniprocessor kernel I compile seem to work fine,
and my friend was running NT4 with both processors.
After some long hours scouring this group's archives
and other web sources I've found that there seem
to be a number of people who have fiddled with these
boxes but nobody has come to any definite conclusions
as to why these boxes don't work. I'm sending this
note in hopes that we can come to some consensuses as
to whether these boxes will ever run SMP FreeBSD.
I'd really like to be able to run a decent OS on this
box because I've got the chance to get two more CPUs,
and that would really make my X10 scripts fly! :-)
If it turns out these systems are not supported I think
we should put something in our SMP docs (perhaps LINT
and the FAQ) to warn people that these systems can't
be supported.
So, here's everything I know about my
ALR Revolution Q-SMP thus far:
To rule out hardware problems I borrowed an identical
CPU card from a test machine at work and tried various
combinations of the cards with the same results each
time. All three CPUs are the same stepping level and
all three worked (even at the same time) in NT4.
I get the same results in 4.6.2 and 5.0-DP1.
I used the serial console to capture these messages,
and I'll include mptable output below.

Other things that may be of interest:
mptable and the documentation indicate the system is
using Intel's MP spec v1.1
I read in a Linux FAQ that 1.4 is just a tighter version
of the 1.1 spec, does anyone know of other MP 1.1
hardware or P5 systems running FreeBSD-SMP
successfully? Speaking of the Linux, their SMP-FAQ
mentions that older ALRs without P6 CPUs are "iffy",
but doesn't say why.
The manual specifically mentions Windows NT, Netware
SMP, OS/2 for SMP and SCO Unix 3.2.4.2 as all working
with the system. I found a report from Sun indicating
Solaris X86 2.5 works and in several posts from this
group I found there was talk of BSD/OS supporting the
system as well.
In response to an inquiry a few years ago Rik van Riel wrote:
"Note that the ALR uses a custom (non-IMPS) bus. If only
because that's the only way to keep 4 Pentium CPUs in
a cache-coherent state. The documentation for this glue
logic seems to be very hard or impossible to find... "
Can anyone shed light on his comments?
I had to use the MAXMEM option in all of my kernels to
get the FreeBSD kernel to see the full 256MB. I doubt
this is related though because it works fine in the
uniprocessor version.
It's also worth pointing out that it locks up after the
ata0 probe; at that point the uniprocessor kernel
picks up ata1, which wouldn't be odd except that I
can't find a connector for the secondary IDE bus and
NT4 doesn't seem to see anything on IRQ 15.
The 4.6.2-generic kernel reports:
ata1 at port 0x170-0x177,0x376 irq 15 on isa0
This is probably some unrelated weirdness, but it
seems like a weird coincidence...
Thanks everyone,
anthony
