I compare 2 output of linux command pci
from both Linuxbios booted linux and a regular bios booted linux.
There are no IRQ assignments for lots of devices including IDE
controller, SMBUS.
Does linuxbios assign IRQs at all in the code?

In our case we'd use etherboot to Load the kernel (which doesn't handle
interrupts) then Once kernel was loaded we'd see the problem. This Was
fixed by fixing the irq table.

It almost certainly is wrong, unless all the wires on the machines are
absolutely identical. I am willing to guess

well, that was the other possibility I was going to mention, on our first

that's the interesting part. What happens is that once init is running
and
things get a bit more formal, things start to slow down. There are lots
of
causes we've found for this, but interrupts is typically the big one.

I got the keyboard controller problem fixed by enabling Keyboard
separately (Not through the PNP devices list). Since now the PNP devices
don't get enabled at all. For now it's ok because we need only serial
com port and keyboard. But I will love to have the code for SMSC if you
have one
one possibility is that you are getting no serial interrupts, so the
serial I/O is happening only very rarely.
You're going to need to fix your linuxbios burning up so that it is built
correctly.
One question, again, as I forget: what mobo is this?

This is our proprietary mobo. In case you want a quick glance,
http://www.nexcom.com/product/nex/nex7220/
North Bridge: E7501
South Bridge: ICH3 - S
SuperIO: SMSC(LPC47B27x)
I base on the code for tyan/s2735.
If it was the serial interrupt, why didn't it happen earlier? It starts
getting slow at
