Subject: Disable cache on 74xx
Date: Wed, 19 Feb 2003 15:52:01 -0500	[thread overview]
Message-ID: <200302191552.01911.waite@skycomputers.com> (raw)


Hi all,
	I am trying to hunt down a memory controller configuration problem and I have
been asked to disable all caching so as to remove it from the equation. I can
easl disable L2 but when I start ucking with the WIMG bits to set cache
inhibit, The kernel panics with stack overflows. Does anyone know where or
what I have to set to disable caching?

Thanks
Brian
