--- Comment #10 from Anthony Williams <anth...@adfw.co.uk> --- Hi, acpi_ibm_load="YES" is set in loader.conf and has been for several years - this install started off originally as 12.1-RELEASE back in 2019. I believe I did try disabling it during my testing, with no change in behaviour. I've tried a fresh live USB image as well, which has the same problem. I'll have a dig through the BIOS to check for anything relevant to MPS. It turns out there is also a BIOS update to apply. I'm currently running BIOS rev. 7UET92WW (3.22), the changelog for 3.23 is described as "microcode update", so I'll apply that and see what happens. -- You are receiving this mail because: You are the assignee for the bug.
