This bug (activating show_mem) can be reproduced without the dd on tmpfs. From a initial ramdisk containing only a shell, some libraries and the following init script: : #!/bin/sh : echo Loading.... : sleep 60 Pressing shift+scroll lock during the sleep generates an oops at the beginning of the show_mem function also. The issue does thereby not seem to be related to any of the kernel code compiled as modules. It pretty much rules out tmpfs itself. > Theory 1 > -------- > Can we eliminate bad hardware as an option?

The kernel has been run on multiple hardware (similar (not fully identical) type though) and memtest86+ has been run for several hours without any trouble. $ lspci -v :00:00.0 Class 0600: 8086:27ac
