[hylafax-users] 2.6 kernel and Multiport boards (MainPine)

[Robert <rns@xxxxxxxxxx>]

I've been messing around for the past several hours trying to get the 
RockForce Octo+ from Mainpine
working on a 2.6 kernel.

All is working well except, the multiport command comes back invalid.

After 'Several' recompiles of my kernel I decided to search the group.

I found a post (quoted below) by Darren Nickerson of iFax, stating 
basically in 2.6
multiport support is different, you no longer need the mutliport 
statement...
it should just work. He also mentioned MainPain would make a official 
statement
(Which I do not see on their site) is regards to a recommended installation
procedure.

What I would like to know is:

Is anyone running this setup in a production environment?
If so what are your experiences, is it stable?


Thanks,

Chris/Lee,

In kernel-2.4, the *multiport* 'latch' is required. Most major distros 
default
kernels are compiled with *multiport* support, and so the set_multiport 
line
would execute properly (at least when there's no ioport interrupts) and a
kernel recompile would not be required.

This has completely changed in kernel-2.6 ... they've reworked the 
*multiport*
serial support quite a bit.

We've been working with Mainpine to help them develop a recommended
configuration procedure for kernel-2.6, and we each have 2.6-based fedora's
in our labs in testing. So far, it seems like you can run all the setserial
commands _except_ for the *multiport* latch (which is not relevant to
kernel-2.6 and as far as we can tell will never work) and it should 'just
work'.

Look for an update on Mainpine's website once they've finalized their
official recommendations.

-Darren
