>Description:
Here's the panic message:
fatal trap 12:  page fault while in kernel mode
fault virtual address	=0x26
fault code		=supervisor write,page not present
instruction pointer	=0x8:0xf01c8663
stack pointer		=0x10:0xefbffef0
frame pointer		=0x10:0xefbfff00
code segment		=base 0x0, limit 0xfffff, type 0x1b
			=DPL0, pres 1, def32 1, gran 1
processor eflags	=interrupt enabled, resume, IOPL=0
current process		=272 (gzcat)
interrupt mask		=net tty bio
panic: page fault
syncing disks.....30,30,30,30,30, etc   giving up

Then it reboots.  Any ideas?

	

>How-To-Repeat:
Just compile the kernel to recognize 128 megs of RAM and it crashes.  Seems to run ok with only 64 megs being used.


	

>Fix:
	
	
Any help would be greatly appreciated.  Thanks
