That has nothing to do with using a global IRQ array. It just means LASI subdevices can't be redirected individually. They will still be assigned a global IRQ number. PCI devices using IRQ lines below DINO will have the same problem. Ditto for E/ISA support under WAX. thanks for the correction, grant _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
