Loading a newer mach_kernel

[willrea]

Hi,

I was wanting to boot to a / that is formatted as ext4. Compiling the
new kernel and cross-compiling everything into a new mach_kernel went
fine but when booting it hangs at "starting linux"

Any help would be appreciated.

Hi William,

Just wanted to echo your experience. Although personally still using
EXT3, when I've tried the above with a Karmic Kernel, I have the same
hanging issue. I was wondering if the bootloader needs patching to
work with newer Kernels? What Kernel were you trying it with?

I heard there was a grub2 patch floating about somewhere. Perhaps this
is what I need (have already tried installing legacy grub and
recompiling, but no dice)...

Perhaps more experienced hands can chip in?

I did a grub2 patch but that won't help you in this case. The grub2 patch is just for parsing the grub2 config file.

You can get by any problems with grub 2 by creating a menu.lst file with the proper entries (3-4 lines I believe). You should be able to find those entries on this list, if not I have them at home and can post them. But if your kexec is happening with the proper options then it would not help in that case.

Hi Robert,

Thanks for the reply. I initially tried it with a self-constructed
menu.lst but I had the OP's problem with hanging. So then I removed
grub2, installed legacy grub, but still had the hang with the system-
constructed menu.lst...

The Mach_kernel seemingly compiled correctly using the Darwin Cross
tools. I even tried it on a mac... But again, the resulting
mach_kernel boots with the same result...

Do you have any pointers towards making this work with Karmic... or
even a way to test the mach_kernel that will yield some useful debug
info? As I say, at the moment it will just sit there at starting Linux
for ever (or until the power is yanked!) and I can find no useful way
to interact with the box in this state to work on the problem... are
there tools that can test the file?

Anyway I would still like to have a go with your grub2 patch if
that's ok.... Do you have a copy online somewhere?

Sorry it took a while to respond. I do not have the modified files
online anywhere, just submitted them to Scott. I'll find a place to put
them for you if you want to try them out.

I unfortunately do not have any experience with troubleshooting the
mach_kernel. I run all mine with ext3 so I haven't done any ext4 stuff
on the atv.
