BTW, for lkml readers: this was in original post: ================================================= We have a number of machines with identical dual PPro 200 mainboards. They all run fine on 2.2.13 kernels. Trying 2.4.18,2.4.19,2.4.20-pre7 and even 2.2.19, the same problem shows up: With SMP activated in the kernel, I get the boot-messages --------- PCI: PCI BIOS revision 2.10 entry at 0xfb0a0, last bus=0 PCI: Using configuration type 1 PCI: Probing PCI hardware PCI BIOS passed nonexistent PCI bus 0! PCI BIOS passed nonexistent PCI bus 0! Limiting direct PCI/PCI transfers. --------- Afterwards, everything runs fine, except that PCI seems to be only half-way functional: network-cards don't give any error messages but behave just as if the cable was disconnected scsi-cards give strange errors (don't recall what exactly) With SMP disabled in the kernel, everything works just fine. ================================ > > Post your .config and dmesg > > Here they are.

Can you try to boot 486-optimized kernel? Can you remove one CPU and run SMP kernel on UP configuration? -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
