Plug in a PS/2 mouse, and it works. See product errata for the AMD-768 (#10): "Multiprocessor system may hang while in FULL APIC mode and IOAPIC interrupt is masked" I'm currently running similar setup (same MB, Redhat 9 + 2.4.22-pre7) without any problems. If the PS/2 mouse is removed i get exactly the same problems as you described. And it's not only the IDE that is affected. E.g. doing 'ifdown eth0' causes the system to hang (at least for me it did), so turning off the DMA is not a solution. > Do I have to upgrade the glibc or any other system components? no.

Which mobo's are said to be reliable? Same problem appears with all motherboards using AMD 768 (rev B1 or B2). (Correct me if i'm wrong. Maybe some manufacturer had made workaround for this problem...) Cheers, KM
