I'm not in the habit of upgrading BIOS/UEFI on my computers. (I do have {amd64,intel}-microcode installed.) What old or buggy code would I be running when booting a linux installation? (I accept that Grub has to run, and the kernel and initramfs be found, initially.)
Your BIOS/UEFI may perform boot-time memory training to adjust memory frequency and voltages. I think it might also be responsible for setting CPU and other chipset voltages during operation. These have a profound impact on system stability. I always upgrade my BIOS/UEFI to take advantage of any improvements recommended by the manufacturer.
