Message-id: <200907061056.00229.gene.heskett@verizon.net> Date: Mon, 06 Jul 2009 10:56:00 -0400 From: Gene Heskett <gene.heskett@...izon.net> To: Linux Kernel list <linux-kernel@...r.kernel.org> Subject: OOM killer in 2.6.31-rc2 Greetings all; I had to hard reset this box just now as there was no response to a ctl-alt- bksp when X was un-responsive this morning. I had built a 2nd version of the 2.6.31-rc2 kernel last night when I found the video stuff appeared to have been moved in the .config and my pcHDTV-3000 cards modules were not being built, but are now. That kernel was installed, and if at some time in the night a module was needed, it would have been available, but I can't make a solid connection. This machine will always be marked as 'tainted' because any bios update that fixes the very early boot time oops, also leaves me with a machine that will crash hard in 30 seconds to 3 or 4 hours. The fixes done by the oops make it generally dead stable for weeks.

I've no idea if the rebuilt (with v4l drivers now) will also crash. It feels normal. And looks normal in htop's display, using 538M of 4096M, no swap used yet. >From my .config: # grep MEM .config CONFIG_SHMEM=y # CONFIG_MEMTEST is not set # CONFIG_NOHIGHMEM is not set # CONFIG_HIGHMEM4G is not set CONFIG_HIGHMEM64G=y CONFIG_HIGHMEM=y CONFIG_ARCH_FLATMEM_ENABLE=y CONFIG_ARCH_SPARSEMEM_ENABLE=y CONFIG_ARCH_SELECT_MEMORY_MODEL=y CONFIG_SELECT_MEMORY_MODEL=y CONFIG_FLATMEM_MANUAL=y # CONFIG_DISCONTIGMEM_MANUAL is not set # CONFIG_SPARSEMEM_MANUAL is not set CONFIG_FLATMEM=y CONFIG_FLAT_NODE_MEM_MAP=y CONFIG_SPARSEMEM_STATIC=y CONFIG_X86_BOOTPARAM_MEMORY_CORRUPTION_CHECK=y CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG=y # CONFIG_BLK_DEV_UMEM is not set # CONFIG_INPUT_FF_MEMLESS is not set CONFIG_DEVKMEM=y CONFIG_FIX_EARLYCON_MEM=y # CONFIG_HW_RANDOM_TIMERIOMEM is not set # CONFIG_MEMSTICK is not set CONFIG_FIRMWARE_MEMMAP=y CONFIG_DEBUG_MEMORY_INIT=y CONFIG_HAVE_ARCH_KMEMCHECK=y CONFIG_STRICT_DEVMEM=y CONFIG_HAS_IOMEM=y In case I have some option miss-set in that, plz advise.
