It seems that updating our machine to 5.4-p5 (RELEND_5_4) has solved this,

building and installing the new kernel and it hasn't gone down since.
Very interesting. We're still at 5.4-p1. The version bump fixes didn't look
like they were addressing stability, only security, but why not...
This
is with SMP, ACPI and HT enabled on a Dell 1750 with two 3GHz Xeons.
Pretty identical to our system.
The
2850 has been rock-stable running 5.4-p3.
And you never ran previous versions on that system?
Whatever is was, it seems to
have been fixed around that time.
Could be that your issues are amd64 related. We run the i386 branch
because we need stable systems, not 64bit.
I have indications that the problems have occured equally on i386 and
amd64, and that amd64 is considered stable, but that might not be quite
true?

The issue still persists on 4.11 though. Can somebody explain what the
ACPI fixes were around that time and if they will be backported to 4.X?
Regards

hello list,
For the past year we've been running several Dell PowerEdge 1750 servers
on FreeBSD 4.10, 4.11 and 5.3. All these machines have dual Xeons
running
with HT enabled. This install has proven to be unstable in that the
machine will reboot between 3 days and 170 days without apparant reason.
No log is written. Other machines we have with a single CPU (HT enabled)
do not experience this problem.
As it is present in both 4.x and 5.x and googling the last year has not
revealed similar experience I'm consulting this list. As all of these
machines are productions machines that have a continuous load (not
heavly
load, but a light average - some peaks) it's not easy to experiment with
HT setting etc. I dislike driving to the datacenter for locked systems
with fubarred kernels ;-)
The only error i've ever seen just before a reboot is "bge0: discard
frame
w/o packet header" on the 5.3 machine.
Late comment while browsing the list for tips...
No good clues, I'm afraid, but we have a 2850, and it is far from stable,
crashing within hours when running SMP, often but not always under high
load. Single CPU works like a charm. This is very annoying, to say the
least. See my posts on amd64@ around June 15.
FreeBSD 5.4p1 (amd64). Dell 2850 with dual Xeon CPUS, EM64T.
