dead facter process while executing kmod fact

[QueerCodingGirl]

Facter, and therefore the puppet agent process hang in the dead state when executing the kmod fact. The output just stops and no error is generated.

Environment:
OS: Ubuntu 18.04 virtual machine
Agent: Puppet 7.23.0
Facter 4.3.0 (bundled with the puppet agent)

I added some debug lines to the fact and found out it dies when it tries to read from /sys/module/kvm_intel/parameters/eptad.
Changing the rescue line to catch all exceptions did not help.

The line that triggers the error:

puppet-kmod/lib/facter/kmod.rb

Line 27 in 754ab27

kmod[directory]['parameters'][param] = File.read("/sys/module/#{directory}/parameters/#{param}").chomp

After excluding the eptad parameter, it fails on the next one (flexpriority), so i guess it may fail for the whole kvm_intel module parameters.
