The bug is documented in the Dino3.1 Errata. I don't recall if that got published. Search the mail archive for "corruption". With a dino2.1, I'd be pretty certain your box will be affected. My understanding was HP replaced old dino chips with 3.1 versions. For customers, this meant a board swap. Note that upgrading PDC (firmware) may render PCI unusable. PDC won't let you boot (or get to PDC prompt) the box if dino is rev 3.0 or lower *and* a PCI card (except HP graphics) is installed. It'll halt and print something about PCI and "contact local HP support". grant Grant Grundler parisc-linux {PCI|IOMMU|SMP} hacker +1.408.447.7253
