I won't have access to the system until then and I don't want to try doing it remotely, especially since I have not played with boot configuration on V5. This is quite possibly $PIR related since it worked fine with V4, but only works with ACPI on V5. I can't say just when the problem with non-ACPI boots started as I had not had occasion to try a non-ACPI boot with V5 before a kernel of June 13, 2004. The June 13 kernel failed to deal with interrupts from my network card as does RELENG_5. FYI, no apic or smp in the kernel. ASUS P5A w/ K6-3@450 CPU with only Matrox AGP card, Ensoniq PCI sound and 3Com network cards added to the system. I have not tested the sound card without ACPI. Thanks! -- R.
