UEFI implementations; this is not a universal problem with the UEFI
design or anything.  It is unclear (just "some MSI boards") which

other isolated UEFI implementation problems before (some Samsung laptops
for example, with a particular UEFI version and Linux kernel driver
version plus a samsung-laptop driver enabled).

This isn't meant to diminish the impact; certainly UEFI is proving to be
problematic in ways the BIOS wasn't (although the early days of "IBM
compatible BIOS" implementations also had weird issues from time to
