Hello, i ran into a similar problem when recently trying to install 8.0R on an embedded system. We've been using this hardware for a couple of years with FreeBSD 4.11 and didn't see any problem like this. Disabling the memory hole (15-16M) solved the problem here, but that shouldn't be a solution. I wonder whether it's a loader-, or a BIOS-problem, since memory-allocation should respect reserved areas.

Your system's SMAP is kind of weird (it has a very small region above 1MB, so it may not deal well with "large" kernels, though I thought it had enough room for at least a 12MB kernel. Hmm, the size of the kernel file may be deceptive though since it does not include BSS. I wonder if it is trying to load the symbols after the BSS. -- John Baldwin ______________________ -- *********************************************************************** * demig Prozessautomatisierung GmbH * demig Anlagentechnik GmbH * * * * * Anschrift: Haardtstrasse 40 * Haardtstrasse 40 * * D-57076 Siegen * D-57076 Siegen * * Registergericht: Siegen HRB 2819 * Siegen HRB 5532 * * Geschaeftsfuehrer: Joachim Herbst, * Joachim Herbst, * * Winfried Held * Winfried Held * * Telefon: +49 271 772020 * +49 271 772020 * * Telefax: +49 271 74704 * +49 271 74704 * * E-Mail: info@demig.de * at@demig.de * * http://www.demig.de * http://www.demig.de * ***********************************************************************
