Hi, > Sorry I took so long to get back on this. In a nutshell, this is >what I have figured out: > > standard SMP kernel APIC_IO SMP kernel >de0 in, MP v1.1 enabled works hangs right before init >de0 in, MP v1.4 enabled hangs hangs so there is another problem here, I assume this works OK with the UNI-proc kernel? >de0 out, MP v1.4 enabled works works initially, X crashes it ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ as Peter just stated, this could be expected for other reasons involving the npx code. --- >Probing for devices on PCI bus 1: >ahc0 <Adaptec 3940 Ultra SCSI host adapter> rev 0 int a irq 17 on pci1:4 >Freeing (NOT implimented) irq 11 for ISA cards. > ... >ahc1 <Adaptec 3940 Ultra SCSI host adapter> rev 0 int a irq 18 on pci1:5 >Freeing (NOT implimented) irq 10 for ISA cards. this is what we want to see, the code picked up the proper APIC_IO irqs from the MP table! --- and these are what the entries should look like (1.4 made the difference) >Bus: Bus ID Type > 0 PCI > 1 PCI > 2 ISA > >I/O Ints: Type Polarity Trigger Bus ID IRQ APIC ID INT# > ... > INT active-lo level 1 4:A 2 17 > INT active-lo level 1 5:A 2 18 > INT active-lo level 0 13:A 2 19 note how the table both uses the correct PCI syntax AND the 2 PCI busses between 4/5 and 13, ie 4/5 are on pci1 while 13 is on pci0. (although I would be curious as to whether it would still report 2 PCI busses without the 3940 installed...) So the remaining question for this system is why the SMC card hangs the SMP kernel, both APIC_IO and non-APIC, UNLESS it is set for MP spec v1.1 --- > If there's any more information I can supply, or testing that needs >to be done, just let me know.
