A correction... You need to do "echo 1 > /proc/sys/kernel/sysrq" to enable AltSysRq before

/proc/sysrq-trigger is not controlled by /proc/sys/kernel/sysrq
unless some $distro modified that.
You're correct, my mistake. /proc/sys/kernel/sysrq controls the AltSysRq key
sequences, but not /proc/sysrq-trigger. I thought it controlled both.

Hi,
I want to install Kexec/Kdump features in my system.
I am very much new to system related things, and also system programming.
Can anybody suggest me which is the latest version of this tool and
how can I install, configure, and test for a system panic using
Kexec/Kdump?
Thanx
Shan
