vdso: print fatal signals Add the print-fatal-signals=1 boot option and the /proc/sys/kernel/print-fatal-signals runtime switch. This feature prints some minimal information about userspace segfaults to the kernel console. This is useful to find early bootup bugs where userspace debugging is very hard. Defaults to off.
