Re: [lfs-support] Low Level forum
Hi Viktor Engelmann; First, IF You are the Viktor that did the series on building an operating "I want to say Thank You", This series is and was Great.. Second, and the main reason for my Sending You this email, I tried to Register on the LowLevel Forum, and something went Wrong and even though I type in my name (Marty G) and Password, it tells me that I need to Activate it, but, when I try to activate it, it says I can't do that or something is wrong and rejects my attempt to activate.. It's as though I need to activate it to make the activate work.. I think when I originally registered I did something wrong, and so my password and activation won't work .. Would You please let someone know who runs this site, and have them please let me know "How I can get into the Forum".. I have tried another name, but it rejects that as well..

Pierre, thanks for finding the patch. After I'd gone to bed it
occurred to me that I would need to download earlier 5.11-rc kernels
to find which one fixed it, and then do a reverse bisect to find
which commit fixed it (the logic of that always makes me even more
confused than normal), so many thanks for saving me that confusion!
I've now applied that to 5.10.15-rc1 and confirmed it builds and
boots. Gotta go out right now for provisions, will use my other
mail to inform the relevant people that this fixes builds with
binutils-2.36.1 when I get back.
Cheers.

Looks like
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=44f6a7c0755d8dd453c70557e11687bb080a6f21
