Subject: [PATCH -mm] console: console_drivers not initialized
Date: Mon, 25 Sep 2006 14:07:10 -0700 [thread overview]
Message-ID: <20060925210710.931336000@mvista.com> (raw)
I was doing -rt stuff on a PPC PowerBook G4. It would always reboot
itself when it hit console_init() .
I noticed that the console code seems to want console_drivers = NULL,
but it never actually sets it that way. Once I added this, the reboot
issue was gone..
