OK, I've been testing the kernel today. It seems to boot fine with
your fix, but I've been unable to get the YDL5 installation on the
PS3 to start with the updated kernel.
I've done a lot of tests, but the one that seems more "correct" is this:
I built the ps3-linux branch by using the ps3_defconfig as is,
without any changes. Then I ran "make targz-pkg". I copied the
resulting file, linux-2.6.21-rc3-g6a692aee-dirty.tar.gz, to the PS3,
where I unpacked it in a temporary directory.
I put the modules in place and copied the vmlinux image to /boot/
vmlinux-jmerino. I then created a new initrd by using "mkinitrd /
boot/initrd-jmerino.img 2.6.21-rc3-g6a692aee-dirty" and added an
entry to /etc/kboot.conf. I mimic'ed the one for ydltext but
replacing the version numbers with "jmerino", which is:
jmerino.img root=/dev/sda2 init=/sbin/init 3'
Then, the kernel starts up but when it is time to exec init, it says:
Warning: Unable to open an initial console.
I've also tried multiple other things, such as 1. building a kernel
without modules support and keeping everything in it, 2. not using an
initrd at all, or 3. reusing the initrd for the default YDL5 kernel.
All tests failed with the above or with a message saying that the
kernel could not find init (even though it seemed to correctly mount
the root partition).
I'm not sure why this is failing, nor have been able to find a
solution. Any clue?
PS: Is it there any other mailing list more suitable for "Linux on
PS3" questions or this one is fine?
