I am unable to reproduce this on a 16/32 core/thread amd64 box with a MegaR= AID SAS 9361-16i PCIE with the exact same firmware revision. The box also has a Microsemi SAS HBA which seems unaffected by this. System details: Talos II motherboard 2x 36 core (144 thread) POWER9 processors 512GB memory 4k page size MegaRAID SAS 9361-16i PCIE controller (4 disk RAID10 volume, megaraid_sas driver) Microsemi HBA w/4x SSD's The relevant dmesg messages are attached. --=20 You are receiving this mail because: You are watching the assignee of the bug.=
