Hello,
that's me again and it seems to me that the XXpress saga will
come to the end soon -- with FreeBSD final victory, I hope :)
This machine is going to become a mail relay of major importance.
For several reasons, commercial unices aren't an option.
The machine is Big and Nice ;) but only Solaris x86
was able to live successfully on it -- more or less, because
neither Linux nor Solaris were able to recognize _both_ AIC7870 chips,
only the first one worked.
Ok, first time FreeBSD
failed to sit on it and live there; and my collegues are
all Linux-oriented men, they put some fancy Linux distribution
onto this box, with 2.0.30 kernel. Test run: a loaded Squid proxy
caused a silent crash of Linux, no reboot, nothing, just death
with a one-line panic message, after 1-2 days of uptime.
Other Linux kernels -- same behaviour. So now
I got the box again, and -- cool! patch by David Greenman succeeded,
thanks! The first and the most boring problem is solved,
2 AIC chips are recognized.
Dear Stefan, wouldn't you mind commiting a cleaner equivalent
of the pci.c fix below to both code branches, please.
Some questions still remain, though.
I.e.: what are those PCI chips, they are unknown to FreeBSD,
they caused weirdness in the dmesg output below?
Why on the Earth I'm seeing that infamous-since-i386-days "stray irq 7"
message once again?
What does the message: "ahc0: Reading SEEPROM...checksum error",
"ahc0: No SEEPROM available" mean -- is this Ok?
(And will FreeBSD on this machine more stable than the "other OS" was? ;)

Yes, Intel logos as well. I also noticed some references
to a string XPC in the BIOS setup, somewhere under
"Advanced -> ... chipset ..." screen. I have no ideas
what can this mean... BIOS is AMI, version is 1.00.06.BG0
"Interesting" options are:
Force BSP to slot 2 [Disable]
Force XPC Posted Write [Auto Detect]
...
Current XPC Posted Write <Enable>
???

Attempts to do so brought an unusual effect (BTW: BIOS
is capable to redirect it's output to the serial console),
GENERIC kernel started writing to serial port but as soon
as it detected video & keyboard it started writing all the
rest there... :)

No. This system is for us -- and it _should_ be ready 2
weeks ago to start a "test run", with some simple
functions like web proxy running there, while the rest
details of the configuration are being done.
