sysrq configuration not honoured
Last modified: 2013-09-12 15:39:30 EDT
Description of problem:
My machine just hanged on poweroff. As I had enabled sysrq before, I've tried to halt it via the magic key combos. Bad luck, the only thing I could do was sync.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. # echo "kernel.sysrq = 1" > /etc/sysctl.d/sysrq.conf
3. $ cat /proc/sys/kernel/sysrq
You can use the following to work around the bug:
# cp /usr/lib/sysctl.d/50-default.conf /etc/sysctl.d/
# sed -i 's/kernel.sysrq = 16/kernel.sysrq = 1/' /etc/sysctl.d/50-default.conf
but there are multiple settings in that file, what if something changes in the future and the change will go unnoticed due to the local copy?
