Hi Ojab,
Can I get output of 'lspci -vvv -s' for LSI SAS2 card?
On my Supermicro system, I have enabled ASPM in system BIOS but still
in lspci output I see this ASPM was disabled for my SAS2 HBA card
which has Phase19 firmware (i.e. 19.00.00.00) as shown below,

So, Can you also try once with Phase19 firmware.
Thanks,
