Or all of RedHat 9 kernel versions for smp

How reproducible:

Additional info:
This computer has dual 1GHz Pentium 3 processors on the MSI 694D Pro2 mainboard.
It boots fine using the single cpu kernel.  RedHat 8 smp kernel ran fine on this
computer.

Comment 1 Dave Pierson 2003-10-27 20:41:55 UTC
Fixed the problem.  For some smp machines running RH9 you need to change the bus
speed and cpu clock speed to know values in the bios.  For the above mainboards
the following settings must be made in the Frequency/Voltage Control part of the
bios:

"CPU Host Clock (CPU/PCI)" set to "133/33Mhz (Spd on)"
"CPU1 Clock Ratio" set to "x7.5"
"CPU2 Clock Ratio" set to "x7.5"

Then the smp kernel will load without any troubles.
