Kernel panic when pressing alt+PrtScn+c in Ubuntu
1 points by holms 4604 days ago
What is this? Even when screen locked I've got kernel panic. Why sysrq is turned on by default? How can I trust Ubuntu competence after this kind of stuff.

according to http://en.wikipedia.org/wiki/Magic_SysRq_key PrtScn+C means "Perform a system crash. A crashdump will be taken if it is configured."

sysrq ftw. Really useful option. AFAIK alt-sysrq-e and -i are disabled by default in new kernels

according to ubuntu documention you need to press alt+PrtScn simultaneously for any sysrq action

why you need this in the first place? I think I'll troll some colleagues around. Although screen is locked, I'll just push alt+PrtScn and "c" to create a kernel panic. Cruel? Yes. Who's problem is that? - CANONICAL
