Description Job J. van Gorkum 2001-10-27 17:30:23 UTC
Description of Problem:

system installed perfectly, after the reboot to the SMP kernel the system
hangs when starting a compile (anything) a few files are processed then the
system freezes... 

Version-Release number of selected component (if applicable):
base 7.2 kernel from CD and 2.4.9-7smp

How Reproducible:

Steps to Reproduce:
1. boot system
2. compile any source

Actual Results:

Expected Results:
blazing fast compile

Additional Information:

systemboard is a ASUS XG-DLS (bios version 1013) 512 MB

attached a lspci -v ouput

P.S. when the 2nd processor is removed the system works perfectly (as it
did with 7.1/7.0/6.2/etc...)

I did the following:

- Installed the 2.4.9-7smp kernel
- removed 1 processor (and replaced it with the supplied FSB terminator)
- boot the system (leaving IO-APIC enabled)

system is runnig fine for 2 days

still when I reinsert the 2nd processor an generate a High CPU load (make -j4 on
any source) the system freezes (alt sysrq does not work)

what kind of information do you need of me to resolve this bug, It's waste of
money buying a $800 processor and being able to use it!

Is this the way you help a paying customer? 

We have resolved the issue on our own... 

If you want to close the bug, you will have to do it yourself.

I have a similiar problem on my system which is an Intel Celeron machine 
running SMP on a patched Abit BP-6 motherboard.  The system actually runs fine, 
complies software, and whatnot.  However, after running for anywhere from 20 
mintues to 2 hours, the Ethernet card will cease speaking to the network (Intel 
EtherExpress Pro 10/100) or the machine will lock up entirely.  This seems to 
me to be a problem with interrupt handling in the shipped kernel (2.5.9-13smp 
in this case).
