I've been trying to fix a problem I've been having on one of my systems.  
Maybe one of you have encountered something similar.

When I first got this Soyo Dragon motherboard last year, I installed Mandrake 
9.1 on the system and encountered a weird hang problem.  At some point (not 
immediately) when the screen saver was running, the keyboard lights would 
start flashing and it would be completely locked.  (Is this the usual sign of 
a kernel panic?)  This problem would happen fairly frequently.  Shortly 
afterwardI had to back off to Mandrake 8 due to problems getting Kylix 3 
running on the newer distro.   At that same time I'd just discovered (and 
disabled) the ACPI option in the bios, so I thought I'd fixed it.  Recently I 
set up 9.1 in a spare partition so I could run Eclipse.  In 9.1, the problem 
was back.  It also happens in Red Hat 9 and Red Hat 7.3 - the common thread 
appears to be kernels that are newer than 2.4.3-20.   But unfortunately I 
can't find anything in the log about that, I just see normal stuff like cron 
messages.  One thing that  makes me suspect power management was the 
following, which I see occasionally in the log files on all the different 
distro installs:

Mar  6 04:06:41 vaughn kernel: Uhhuh. NMI received for unknown reason 3d.
Mar  6 04:06:41 vaughn kernel: Dazed and confused, but trying to continue
Mar  6 04:06:41 vaughn kernel: Do you have a strange power saving mode 
enabled?

I suppose that may be totally coincidental, but the hang problem has never 
happened while I've been actively using the machine.  (The other oddity about 
this system is that sometimes when I reboot it, it hangs on the reboot, and I 
must press the reset switch in order for it to come up.  That's probably not 
related, but you never know.)

Is there a way I could make the logs more verbose so I could get a handle on 
this problem?  Another approach might be to run some sort of a cron job which 
would keep the system from ever being inactive for too long.  That would 
allow me to test my hibernation theory.

Thanks,
Vaughn Treude
