sensors-detect in what package?

Ultimately if there's a userspace crash you should use abrt to report
a bug against that package
It is not crash in user space. Execution of the user space binary sensors-detect is causing kernel space OOPS.
This is what is printed on the terminal on executing this program:
--
[root@rpi3 ~]# sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
modprobe: FATAL: Module cpuid not found in directory /lib/modules/4.14.0-0.rc6.git2.1.fc28.armv7hl

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):

Why it needs to be reported over abrt?
I've removed those packages from my image trying to minimize size of the image.
Just had time to back to my RPi3.
Latest kernel is OOPSing in bcm driver on boot:
