Hi,
Hello Mart,
I compiled 5.0.5-rt3 last week, and after rebooting I found that efivarfs failed to mount. Loading the efivarfs module gave me a 'device not found' error. Rebooting into 5.0.0 (no rt) and efivarfs automounted as usual. Trouble is, I have no experience with bisecting between two different branches, so I have no clue on how to start debugging this. Anybody want to throw me some pointers?
Linux-rt is disabling EFI runtime by default because it may increase the latency of the system (see [1] for more details).
You can override the behavior by adding "efi=runtime" on your kernel command line. Cheers, [1] https://marc.info/?l=linux-rt-users&m=155379809327926&w=2
