I have installed FreeBSD 5.4 RELEASE and upgraded to -STABLE on a DELL PE2850.
FreeBSD 5.4-STABLE #1: Wed May 25 23:43:12 BST 2005
CPU: Intel(R) Xeon(TM) CPU 3.20GHz (3192.22-MHz 686-class CPU)
real memory = 5100273664 (4864 MB)
avail memory = 4189892608 (3995 MB)
MPTable: <DELL PE 016D >
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 6
amr0: <LSILogic PERC 4e/Di> Firmware 516A, BIOS H418, 256MB RAM
I have disabled ACPI HTT and enabled PAE to make the whole system memory
available.
However the problem I have is the system can crash at any moment, and is not
load related. As the crash info below is when the machine was in an 100%
idle state.

#############################
I have tried to install other versions of FreeBSD.
4.11 Release (Doesn't see all available memory even with a kernel patch)
5.4 Release (Crashes at random times, but mainly under load, running squid)
Does anyone have similar problems or have found a work around?
