Subject: Re: [Fastboot] [CFT] kexec syscall for 2.5.43 (linux booting linux)
Date: 22 Oct 2002 00:04:59 -0600 [thread overview]
Message-ID: <m1ptu3t3ec.fsf@frodo.biederman.org> (raw)
In-Reply-To: <m13cqzumx3.fsf@frodo.biederman.org>
Digging further into the one failure I can reproduced, I have
found a very weird failure case. The kernel code dies after switching
into 32bit mode. I found this boot setting the setup.S hooks and printing
a character to the serial port whenever they were encountered.
I will release another version of kexec-tools shortly with a -debug switch
to enable this debugging, and anything else I can think of. For the most
part I have avoided printing messages out the serial port because not
everyone has one, or has it setup as a serial console.
But if I enable it just on a debugging switch it should be o.k. and help
quite a bit with figuring out why some machines fail, and others do not.
