This error has happened after only 4 days, for example. I have managed to obtain "SysRq-M" output before the box had a chance to oops or crash, but I don't know how useful this might be. Does anyone have any other suggestions for tracking this problem down? I am already compiling with CONFIG_DEBUG_HIGHMEM.
