Message-ID: <4B363EEE.8020108@blueyonder.co.uk> Date: Sat, 26 Dec 2009 16:50:54 +0000 From: Sid Boyce <sboyce@...eyonder.co.uk> To: linux-kernel@...r.kernel.org Subject: Re: All kernels after 2.6.32-git10 show only 1 CPU ** Fixed in 2.6.33-rc2 ** Something is weird on the 2P box. Using the openSUSE kernel 2.6.32-3-default and early 2.6.32-git kernels on the 2P box, I see 2 processors. Same if I boot from the install DVD. Using 2.6.32-git10, 2.6.32-git15, 2.6.33-rc[12] the box hangs solid at various places during boot. When I first booted up 2.6.33-rc2 after using the openSUSE 2.6.32-3 .config as the basis for "make oldconfig", the kernel booted fine with 2 CPU's, second and subsequent reboots, it locks up solid. Later I shall try to get some output from a serial console. tindog:/usr/src # uname -r 2.6.32-git1-smp I shall also progress through the kernels to see exactly which introduces the problem where a kernel will boot one time and not other times and why only one CPU shows when those kernels boot. Regards Sid.
