[arch-general] Arch shutdown because of firefox

[Handsome Cheung]

hi all,

I am a newbie for ArchLinux.

My computer often shuts down suddenly when I browse web site. It brings me
to TTY and said "The system is going down for system halt NOW!". I found
that is because of  the crash of flash plugin of firefox.

And my question is why the crash of firefox can cause my computer shuts
down?

PS. my system environment: Arch + awesome, no DE.
Thanks!
