>Organization:

>Environment:

	P166 with 64MB EDO 
	256k pipeline burst cache
	Motherboard is a GA-586ATE/ATM
	AHA2940W SCSI Controller
	1.2GB IDE HDD (system disk)
	4.2GB SCSI HDD

>Description:

	The kernel fails to compile when this machine has 64MB of memory 
installed. Works fine with 32 and 16 Megs of memory. Works with 64MB if the
external cache is turned off.

>How-To-Repeat:

	Compile the kernel with 64MB of memory and external cache enabled.

>Fix:
	
	Decrease memory or turn external cache off.

 You have either bad memory or a bad cache.  It's not a FreeBSD
 problem.  (Generally, anything that starts working when the cache is
 turned off is more than likely a symptom of a bad motherboard.)

 Thanks for the reply. You guessed the problem, it is the motherboard. I just
 found out that there are known problems with the brand that I have when running
 some UNIX flavors on them. Cheers
