I fixed the problem on my 4801's by having noticed a correlation with
psm and hangs on my laptop, and
thought there may be a LOR or such involving the keyboard driver and/or
kbdmux. Since a 4801 has no need
of those drivers, but *does* contain the hardware they control, just
with no external peripherals connected, I tried
configuring the Soekris kernel with all vestiges of atkbdc, psm, kbdmux,
sc, and such removed. This did appear to fix the hangs.
Hmmm... not for me. This is my kernel config for the hanging net4801s.
It is being in use for a couple of years now and I didn't change it

As you see, no atkbdc, psm, kbdmux, sc, etc.... but still sporadic
hangs... :(
Every 2-3 days matches mine mostly. My daughter was getting tired of
rebooting it.
I backed the source for that server and my laptop to RELENG_7 as of
20081201000000. This fixed the laptop, but I haven't recompiled the
soekris since reverting. At least most of the problem appeared in
either late Nov or early Dec. with what matters for my laptop after Dec
1. So both soekris are running on releng_7 as of just after the release.
You *do* have agp... (and eisa; I don't remember if I removed that or
not. I didn't)
Mine also has apic but not SMP. (there are lots of apic's in ich
chipsets that help route pci interrupts without being SMP.) I have
CPU_SOEKRIS and CPU_GEODE also. I did leave uhid in mine to handle the UPS.
ukbd appears to count. Maybe ums.
Mine is running on a cf with nfs for updates. (I do compiles on the
co-located file server).
I have ALTQ and netgraph compiled in, with most ALTQ options but
netgraph options commented (since it will load modules as needed).
(ALTQ is needed since this is a nat firewall with voip behind it.)
