That would suggest two things: 1) the box HPMC'd in both cases - look at PIM dump for more info 2) we have a bug in our HPMC handler that PDC tries to call (in real mode). Perhaps one of the asm gods (or even demi-gods :^) could look at hpmc.S and the path to get there. grant Grant Grundler parisc-linux {PCI|IOMMU|SMP} hacker +1.408.447.7253
