Hi, I'm seeing a problem with 4.7 where, very rarely, the system seems to "lockup". No panic is given. I was able to track it down to all processors were halted (in the idle loop) since machdep.cpu_idle_hlt=1. The system is a 2 physical XEON procs with hyperthreading enabled. The system was behaving as though the 8254 system clock was not going off. The only thing I can think of is some kind of lapic problem where the interrupt is not being delivered to the CPU. Any others encounter such a problem? th...

Dear Sirs. It seems to me a never ending story. We run a box with a TYAN Thunder 2500 Dual SMP mainboard, 2GB ECC Tyan certified memory, AMI Enterprise 1600 RAID adapter and additional Intel 1000/Pro server type (64 bit) GBit LAN NIC. With FreeBSD 4.8 this was stable, but to achive this state was really hard! It is a story similar to that what happend when we changed towards FreeBSD
