This is then pre appendix D, and thus a problem (tho not necessarily the cause of your random locks) as it prevents efficient usage of the IO APIC. I would suggest seeing if you can get a BIOS upgrade from supermicro. For the random locks, try slowing down the memory accesses in the BIOS. this has the smell of a hardware problem of some sort. --- I don't seem to have any recent mptables for the supermicro series (thought I did, but I must have lost them somewhere...) Could any user's of SMP and supermicros send an 'mptable -dmesg >outfile" to me. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
