When I try to boot an amd64 kernel built from the latest sources it drops into the debugger with this message: panic: mpacpi_findintr_linkdev: irq mismatch I can reproduce this every time if someone wants to have me run some commands in the debugger. A 4.0_RC4 (GENERIC) kernel boots fine. -- D'Arcy J.M. Cain <darcy@NetBSD.org> http://www.NetBSD.org/
