Description of problem:
I'm running a dell server (R610) with an attached disk array using a PERC H800
under mageia 7.
with kernel 5.1.x, no problem
If I upgrade to kernel 5.2.x (tested 5.2.7 and 2.2.16), I have the following error :

Yeah, 
I have hit the same issue when upgrading one of the servers in the Mageia buildsystem, forcing me to use an older kernel to keep the buildsystem going.

I will be building a 5.3 series kernel soon-ish to see if that works better before taking the issue upstream...

I have tested the new kernel 5.3.1-2.mga7, and it is working for me too.
Thanks !
