Hey Thomas,
Are you able to double-check that bisect? I'm not at all sure how
that particular commit could trigger the issue you're seeing. Some of
the others, certainly. It might be worth trying a couple of times
before marking something as "good", in case there's a timing aspect to
the problem.
Thanks,
Ben.

please CC me, otherwise I might not see your message. The bug is very
clear, I boot my machine, the screen turns black as soon as the X server
is booted and the system does not ping anymore. I rebooted several times
before the bisect and the bug always hit me. For my taste the offending
commit is to large. So maybe I can split it in multiple smaller commits
and than debug it. However I'm currently out of the office, so maybe
tomorrow. If you do any progress on this, please CC me in order to avoid
duplicate effort.
Cheers,
Thomas

8777c5c11764d8336d8270f96778158c34c92108 (which is mentioned as the
first bad commit above...) is a tiny commit, so I have no idea what
you mean by "too large for your taste".
In any case, I encountered the oops myself earlier (absolutely nothing
to do with that commit) and fixed it here. I've sent it onto Dave for
the next -fixes merge, so hopefully it'll help your case too.
Thanks,
Ben.

for example I would not export a symbol and do something else in the
same commit, but would split them up in two. I do the minimum work per
commit without breaking compilation or functionality. That way it is
easier to identify issues later on.

Can you please send me your fix. I can reboot my machine remotely, but
only once. That way I can tell you if your fix works, or not.
