Fix for UEFI + Hardware RAID + Linux = megaraid_sas io_page_fault

Short remider to myself and the rest of the world:

  • Upgrade Firmware to latest (yes, 2013 is better than 2011)
  • Set UEFI to UEFI ONLY! It's 2021 as of now, so nobody should be using BIOS anymore. Seriously.
  • Boot Kernel with iommu=soft option (in grub press "e" if you are locked out already)
  • Put iommu=soft boot option to /etc/default/grub (GRUB_CMDLINE_LINUX_DEFAULT) and do a update_grub && reboot to make it a permanent fix
  • If running AMD + Proxmox, use amd_iommu=on iommu=pt
  • If running INTEL + Proxmox, use intel_iommu=on iommu=pt
