Tried test8 and, now, test9 and both exhibit same problem.

The issue seems to be related to the PnPBIOS support under the Plug and
Play Kconfig category. When enabled I get a crash of the form:

Yes. The crash happens inside the BIOS itself, and the kernel doesn't
really have any control over it. The most Adam could possibly do is to
avoid calling the BIOS (or at least avoid _certain_ calls), but that would
require knowing what it is that triggers it.

One of the most common triggers is requesting for the dynamic (currently
assigned) resource information. This tends to happen with particular device
nodes, from what I've seen typically the mouse controller, but I don't have a
large enough sample space to make a generalization. I've made some
modifications to the PnPBIOS call function in the past and they seem to solve
this problem for many of the buggy systems.

Has PnP support ever worked for you on this board? Sometimes the solution
is to just say "it's dead, Jim", and just not enable it. There are few
enough systems that actually want PnP.

Adam, any ideas?

Linus

I've included a patch that encourages the PnPBIOS to make more conservative
calls and it should help with situations such as this one. I'd like to see a
dmi_scan for this system, if it is possible, so I can blacklist certain PnPBIOS
features on it. I've also attached a patch that makes the pnpbios proc
interface an optional feature. The proc interface allows users to make PnPBIOS
calls without restrictions and as a result can cause problems on some buggy
systems. (one example is the recent ESCD problems posted on lkml) Finally, the
Kconfig help has been updated to better reflect this viewpoint.

Please let me know if any of this helps. I'd predict it will boot properly with
the first patch applied.

Thanks,
Adam

Sorry it took me so long to get back but work is taking up most of my free time as of late. In any event, I applied the patch to a clean test9, enabled the PNP support and the PNPBios sub option. I did not check the sub option, the creation of the /proc interface. It still crashes by the way. Here's the output.

I don't know if you need all of that again but I figured it couldn't hurt. Some of the stuff looks different from before. As far as the dmi_dump goes, I'm not certain what you want or how to get that. The best I could find out that sounds reasonable is the dmidecode app. I've attached the output of that command. If this is not what you wanted please let me know how to get what you want and I'll strive to get it to you.

Thanks for looking into this,

Gary
