I do not have any experience in kernel programming, but I do have a message
in my /var/log/messages file which advices me to post to this list. This is
the first time for me to visit this list, so don't be too hard too me if this
posting doesn't fit into the common list rules.
The problem appears on a machine using the pretty new ASUS CUVX-D Dual Socket
370 Motherboard, so there may be a chance for an unknown bug ;-). With NMI
watchdog activated, a 2.4.x Kernel is not willing to boot on this machine, it
just stops booting at a very early time, giving the latest message
"activating NMI watchdog ..." and then blocking completely. Therefore, I set
nmi_watchdog = 0, when the system boots properly, but leaves some crucial
message in /var/log/messages:
Feb 19 19:37:17 delphin kernel: testing the IO APIC.......................
Feb 19 19:37:17 delphin kernel:
Feb 19 19:37:17 delphin kernel: WARNING: unexpected IO-APIC, please mail
Feb 19 19:37:17 delphin kernel: to linux-smp@vger.kernel.org
Feb 19 19:37:17 delphin kernel: .................................... done.
This is the reason for my posting in this list. This boot has been done with
a self-compiled original 2.4.1 kernel, without any patches applied. With NMI
watchdog activated, I could also reproduce the problem with a standard
2.4-SMP kernel from the SuSE 7.1 distribution, but booting does not lock up
each time. In one from 5 trials, the system boots even with NMI watchdog
activated. Here is the output of dmesg after booting the kernel 2.4.1 with
NMI watchdog activated:

Let me say, that the system seems to be usable after the boot, but when
starting X, some strange drawings hush over the screen. Afterwards, X is
running properly. Using a 2.2.x kernel this behaviour doesn't appear, with a
2.4.x kernel, it is reproducable.
I do not know if this is interesting for some of you guys. As the board is
pretty new (just one or two weeks on the german market), this might be
interesting for testing purposes. Even if I do not have the capability to
help you debugging, I would be willing to test out whatever you want.
Just let me know if you need further information, or send me your patches and
how to apply them.
With kind regards,
Matthias Kleine
