Description of problem: During boot process using the smp kernel, the kernel panics. Last few lines before panic Code 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 <0> Kernel panic: Attempted to kill the idle task! In idle task - not syncing Version-Release number of selected component (if applicable): kernel 2.4.20-19.9smp Or all of RedHat 9 kernel versions for smp How reproducible: 100% on any computer using the MSI 694D Pro2 mainboard Steps to Reproduce: 1. Boot computer 2. Select smp kernel in grub 3. Sit back and watch it panic Actual results: Expected results: 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.
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.
