Subject: Warning/trace in kernel/smp.c:815 smp_call_function_many_cond

Hello everyone,

I have noticed the following new warning in my dmesg output, I think I
have first seen this when upgrading to v6.14-rc1.

So far I have been unsuccessfull in bisecting it, therefore it would be
nice to get some input whether this is something serious or how I could
debug it further. I have also attached a full dmesg for more context.
