Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org [ Please CC replies to me. ] [ Sorry for the rerun, but I guess everyone was away at the OLS, so I'll try again, operating on the squeaky wheel principle. ] Before you hit reply or erase, no, I'm not talking about the machine not getting past the BIOS check complaining that there is no keyboard present. Kernel 2.6.7 model name : AMD Athlon(tm) XP 2400+ motherboard: http://www.ecsusa.com/products/km400-m2.html ... not sure what else might be useful... apci=off added to boot options. Preemptive kernel. In any case, the machine in question does not reboot. I traced the problem down to the mach_reboot but it doesn't get past those assembly instructions. Things do seem to work alright if a keyboard is installed. Otherwise, the machine just sits there, no longer responsive to pings or anything else. This appears to be a somewhat common problem, as I found several other posters discussing it: http://lkml.org/lkml/2004/3/12/248 http://marc.theaimsgroup.com/?l=linux-kernel&m=108868695814658&w=2 any ideas on what parts of the kernel to look at in order to determine what is causing this? I need to fix it, and I don't know where to start looking. Thankyou, -- David N. Welton davidw@eidetix.com
