Ahh, great, thx for letting me know.

Thanks to a proper Link tag regzbot would have noticed that fix once it
landed in next, but it's nevertheless good to know that the fix is
already under review. :-D

Fun fact: sometimes I wish we would not post fixes in new threads, as
that makes it hard to find the proposed fix for anybody that runs into
reported issues and also manages to find the report (e.g. this thread).
But whatever, that's just a detail.

Hello,

Our PASEMI Nemo board [1] doesn't boot with the PowerPC updates 6.4-1 [2].

The kernel hangs right after the booting Linux via __start() @
0x0000000000000000 ...

I was able to revert the PowerPC updates 6.4-1 [2] with the following
command: git revert 70cc1b5307e8ee3076fdf2ecbeb89eb973aa0ff7 -m 1

After a re-compiling, the kernel boots without any problems without the
PowerPC updates 6.4-1 [2].

Could you please explain me, what you have done in the boot area?

Please find attached the kernel config.

Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot:

#regzbot ^introduced e4ab08be5b4902e5
#regzbot title powerpc: boot issues on PASEMI Nemo board
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (the parent of this mail). See page linked in footer for
details.
