Hi,
I have a dual Xeon system. Here is a list of what i have in it:
Supermicro S2DGE motherboard
2 - 400 mhz PII Xeons w/ 512k cache
256 megs PC-100 ram
Gulliemot Maxi Xentor Gamer 32 (agp, TNT2 Ultra chipset w/ 32 megs ram)
13 gig Maxtor IDE hard disk
Ricoh 4x4x24 IDE CD-RW
Creative Labs 6x IDE DVD player
10 megabit combo card (linux recognizes it as a NE2000 PCI card)
Sound Blaster live value
I am running Mandrake 6.1 with full (ie everything) installation. I am
using this computer to run Jaguar, a ab initio computational chemistry
program. First of all, is Mandrake 6.1 a good distribution of linux for
me to use ( I also have RH6.0) and do I have to modify it in any way to
make it more stable with the two processors (i.e. recompile the kernel,
upgrade etc.).
I received the following error message on the console when I was running
several Jaguar jobs at once, after which the computer froze:
[navindra@onyx test]$ Scheduling in interrupt

Aiee, killing interupt handler
I have had numerous lockups and reboots while running several jaguar
jobs at once, but this is the 1st time i have had a message appear on
the console. The lockups/reboots occur randomly, somtimes within a
matter of minutes, and at other times, it takes hours. I have not had
any problems with running a non-smp kernel. I have also experienced a
lockup when compiling a kernel with "make= make -j " in the Makefile.
I would really appreciate it if someone could help me understand what is
wrong in my computer.
Thanks,
Navindra Gunawardena
