Subject: Building Kernel with IDE as Modules
Date: Tue, 11 May 2004 11:07:40 -0700 [thread overview]
Message-ID: <033501c43782$d9dc8300$d100a8c0@W2RZ8L4S02> (raw)
First of all, I know it shouldn't be done! But the reason I'm doing this is
because I maintain the mkinitrd script for the LFS system. This happens with
all 2.6.x up to 2.6.6. Comments and suggestions are welcome.
I noticed the following issues:
On the help for <M> ATA/ATAPI/MFM/RLL support it says the modules name is
ide, I think it no longer exists.
On the help for <M> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support is
ide-mod, I 'm assume the correct name is ide-core
My script worked perfect under 2.4.x, but trying to upgrade it to 2.6.x has
been a challenge in the IDE section
So in theory I should be able to my script load ide-core, ide-disk, then
ide-generic (or the specific chipset driver). When I do I start seeing some
interesting problems. Everything boots up find until another module is
loaded, in my case the tulip driver. I get the following dump
