Currently we pass a string argument to show_kernel_fault_diag() which describes the reason for the fault. This is not being used so just add a pr_info() which outputs the fault information. With this change we get from: | | Path: /bin/busybox | CPU: 0 PID: 92 Comm: modprobe Not tainted 4.12.0-rc6 #30 | task: 9a254780 task.stack: 9a212000 | | [ECR ]: 0x00200400 => Other Fatal Err | to: | | Unhandled Machine Check Exception | Path: /bin/busybox | CPU: 0 PID: 92 Comm: modprobe Not tainted 4.12.0-rc6 #37 | task: 9a240780 task.stack: 9a226000 | |[ECR ]: 0x00200400 => Machine Check (Other Fatal Err) | Which can help debugging.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
