Can you please confirm if you're indicating this is a regression in 4.15?
Or was this present in earlier kernels too?

If it's specific to 4.15, I've got a few steps I'd like you to try to better
characterize.

1) can you please apply https://patchwork.kernel.org/patch/10194287/
and let us know if it helps?

2) If you blacklist dell-smbios-wmi does it help?

Thanks,

\
