The following reply was made to PR i386/84563; it has been noted by GNATS. From: Michael DeMan <michael@staff.openaccess.org> To: bug-followup@FreeBSD.org, dpk@dpk.net Cc: Subject: Re: i386/84563: Panics occur when PAE enabled and >3.5GB memory used Date: Wed, 17 May 2006 13:59:38 -0700 Hi, I and others who have followed the 'disable PAE' workaround seem to experience machines that are more stable, but still crash under heavy load. I have identical machines running e7501 motherboards, one with 2GB of RAM (I pulled the extra out) and another with 4GB and the one with 4GB will crash every couple of months under heavy workloads. I have PAE disabled, USB devices out of the kernel and usbd disabled. I just cvsup'd to RELENG_5_4 today and the patch as described at... http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/i386/i386/pmap.c.diff? r1=1.523&r2=1.524&f=h ...still does not seem to be in the source tree? This bug causes 5.4 systems with 4GB+ of RAM to be unstable and is a critical issue. It seems that this patch works and just needs to applied to 5.4? http://groups.google.com/group/lucky.freebsd.i386/browse_thread/ thread/a44a3dd9a2556725/ce27b27e2a9dc103%23ce27b27e2a9dc103 http://groups.google.com/group/lucky.freebsd.stable/browse_thread/ thread/99978f6cbf071223/136ab31fcd339d5c?lnk=st&q=freebsd+4GB+PAE +thread&rnum=5&hl=en Thanks, - mike Michael F.
