hanging kernel - HPMC problem

hanging kernel - HPMC problem

[Marek Denis]

Hello all,

I am encountering probably quite typical problem with my PA-RISC server. 
Unfortunately, I couldn't find any solution on google.
I am trying to configure kernel on HPPA machine with old PA8000 (with 
300MHz clock) processor.
I managed to install Debian lenny on that machine, configured most of 
the services, owever while trying to recompile the kernel I alwas get 
HPMC bus timeout during the boot. Generic kernel works perfectly, would 
you give me any hints where should I look for a mistake?
I suppose this is only kernel configuration issue.
Here is the .config file that didn't work:

I would appreciate any help

I suggest:
* Remove all add-on cards from the hardware.
* Start with the generic config.
* Enable one thing at a time until it stops working.
* Come back to the list with a list of config options that don't work.

It's a slow and tedious process, but that's the only "easy" way to
solve the problem.

Cheers,
Carlos.

Actually, the only additional hardware is 2x 3COM network cards.
Unfortunately, after removing them from the server my custom kernel also 
hung with 'HPMC bus timeout'.
I will do as you advise, and try to remove one option at once in the 
kernel config.
Anyway, thanks for your help.
