Supermicro P3TDDE (I think; may be a TDDA, but it does have the promise chip).
This board is Via-based and not Intel. Could easily be my problem :-( Don't know about the APIC. Stable runs just fine on the same motherboard (dual-boot, stable on ad0 and current on ad1) including reboot (see below about current's reboot). Not running setiathome at all may or may not have helped; it still died in the middle of a "make -j5 world" (j5 is the best make time on this system) (but did make it through one such make world; died on the second). When it runs, make -j5 world takes about 31.5 minutes for stable and somewhat longer (around 40 minutes) for current without invariants/witness; with invariants and witness make -j4 world is the fastest at just over 2 hours. The hang happens the same with or without invariants and/or witness. Still allowing ACPI; haven't yet tried disabling it. I need to figure out how to get NMI; there are no ISA slots so that isn't a useful way (like an *old* debugger card which I think I still have one of). Another hint (may be more useful) is that either reboot or halt ends up: ------------------------------------- Waiting .... for vnlru Wa ---------------------------------- Sometimes the second line is just "W" and sometimes "Wa", never longer. This appears independent of which cpu says "boot() called on cpu 0 (or 1)" This (like the other hang) is a hard hang, needs reset button to get out. -- Pete To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
