Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> I've spent the last week on debugging a problem with my attempt to upgrade my kernel from 6.2.8 to 6.3.8 (now also with 6.4.0 too).
> 
> The lenghty and detailed bug reports with all aspects of git bisect are at
> https://bugs.gentoo.org/909066
> 
> A summary:
> - if I do not configure wg0, the kernel does not hang
> - if I use a kernel older than commit fed8d8773b8ea68ad99d9eee8c8343bef9da2c2c, it does not hang
> 
> The commit refers to code that seems unrelated to the problem for my naiive eye.
> 
> The hardware is a Dell PowerEdge R620 running Gentoo ~amd64.

> I have so far excluded:
> - dracut for generating the initramfs is the same version over all kernels
> - linux-firmware has been the same
> - CPU microcode has been the same
> 
> It's been a long time since I seriously involved with software development and I have been even less involved with kernel development.
> 
> Gentoo maintainers recommended me to open a bug with upstream, so here I am.
> 
> I currently have no idea how to make progress, but I'm willing to try things.

See Bugzilla for the full thread.

Anyway, I'm adding it to regzbot to make sure it doesn't fall through cracks
unnoticed:

#regzbot introduced: fed8d8773b8ea6 https://bugzilla.kernel.org/show_bug.cgi?id=217620
#regzbot title: correcting acpi_is_processor_usable() check causes RCU stalls with wireguard over bonding+igb

Thanks.
