Basic scenario is default IDE driver, AIC7xxx PCI SCSI connected to HP externel DVD. Using grip (CDDA ripper) to test if system locks up. Unstable systems will normally lock up around track two or three. Stable systems are those which haven't locked up after half a dozen different CDs have been ripped. MB: ASUS A7N8X CPU: Athlon XP 2700+ Memory: 1.5GB (3 x 512MB DIMMs) Disk: Internal 80GB IDE COMPILE SMP ACPI PCI LAPIC APIC RESULT NOTE SMP,PREM ON F SMP,PREM ON NOACPI F SMP,PREM OFF F SMP,PREM OFF NO NO S SMP,PREM OFF NO F SMP,PREM OFF NO S SMP,PREM ON NO NO F 1 SMP ON NO F 2 SMP F 3 APIC,LAPIC S PREM,APIC,LAPIC S * SMP = On (if compiled it) unless nosmp set. Using nosmp with smp kernel causes very odd results. * ACPI = Compiled by default. Set off using kernel paramter acpi=off. * PCI = Kernel parameter. Only used to turn APCI routing off. * LAPIC = Kernel paramter to turn it off (nolapic). * APIC = Kernel paramter to turn it off (noapic). 1. Using APCI PCI routing and nolapic gives very odd results. As soon as the network tries to configure itself it simple hangs (but C-Alt-Del will reboot it). 2. Using the nolapic kernel parameter without disabling ACPI does nothing. 3. Using kernel parameter nosmp on and SMP kernel causes all the lower 16 IRQs to work in XT-PIC mode and the PCI network card to use IRQ 21 with IO-APIC-level. Trying to modprobe aic7xxx hung modprobe but not system. The conclusion to this is the problem is in Local APIC with SMP. I'm not saying this is actually true only that is what the data suggests. If anybody wants me to try some other stuff feel free to suggest ideas.
