Kernel panic when pressing alt+PrtScn+c in Ubuntu

1 pointsby holmsover 11 years 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 <a href="http://en.wikipedia.org/wiki/Magic_SysRq_key" rel="nofollow">http://en.wikipedia.org/wiki/Magic_SysRq_key</a> 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
