Issue with 6.1.8

[Alexandre Oliva]

Hello, Gabriel,

Thanks for your report, sorry it took so long for it to get to me.  The
mailman moderation queues don't get much attention, I'm afraid; most of
the rejections are automatic, and it was only by chance that I happened
to see yours today.

Coincidentally, we've been trying to identify a problem that another (?)
user has reported on IRC, and it may turn out to be the same problem.
So, thank you!

The potentially-relevant bits seem to be:

dell_smm_hwmon: unable to get SMM Dell signature

The backtrace doesn't seem to contain useful information, but the error
quote errors suggest some investigation leads.

It could be useful to compare notes with what others who are running
into this problem.
