Still worth testing with the problem version installed but
with trim disabled to see if that clears the issues, if
nothing else it will confirm / deny if trim is involved.

Hello.
SSD is Intel SSD 530 series (INTEL SSDSC2BW180A4 DC12)
Controler is onboard intel sata controler, motherboard is Supermicro X9SRL-F so
it's Intel C602 chipset
All cache ssd connected to sata 2 ports.
System has LSI MPS controler (SAS2308) with firmware version - 16.00.00.00, but
only hdd's (36 1TB WD RE4 drives)
connected to it.
