It sneaked in a some time ago, I think with 4.8 or so but it took us a
while to find out what is causing it and report it.

The output is identical, without card in socket 0 after boot and with
card inserted after boot (card not detected in these cases), but also
with card inserted before boot (card detected) the output is the same.
Please note that socket 1 is always occupied with a CF card and
working.
This is with CPUFREQ enabled on 4.19

Ok Greg, I made some preliminary tests.
On my side, the PCMCIA insertion is not detected as well. I'm pretty sure though
it was working April 21st, 2018, as I have evidence in my git trees I made the
test.
I will investigate on my side now I know the problem can be reproduced, even if
my case could be some issue on the test platform ...
Cheers.
