Created attachment 244991 [details] .config file for alwaysnever.net Linux kernel 4.8.8 build. I have a small Linux box running a 32bit kernel with PAE enabled, the machine has 8GB of RAM and up until recently didnt have (but now has since upgrading from 4.7.x) a 1GB swap partition. Up until the 4.8.x tree I had no issues at all with custom built kernels on my Debian 8.x (currently 8.6) system, but after about 12 to 72 hours I will start to see the below occur and they will occur without using a single byte of swap. This did not happen with 4.7 or earlier kernels and has happened throughout all of the 4.8.x kernels I have built. Hardware is a Lenovo ThinkPad T400 running the latest BIOS for that platform (3.24 as per details below) - CPU is: Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz Below is a dump of the info from 4.8.8, I will also include one from 4.8.7 below it.
