Subject: Little console problem in 2.5.30
Date: Mon, 19 Aug 2002 02:37:31 -0400 [thread overview]
Message-ID: <20020819023731.C316@devserv.devel.redhat.com> (raw)
Hi, all:
I would appreciate if someone would explain me if the attached patch
does the right thing. The problem is that I do not use the framebuffer,
and use a serial console. Whenever a legacy /sbin/init tries to
open /dev/tty0, the system oopses dereferencing conswitchp in
visual_init().
