First of all, is / on an SSD or hard drive? Try doing a "cryptsetup status /dev/mapper/luks-UUID#". Look for "flags: discards". 2) Should be just discard 3) Should be rd.luks.options=discard 4) Please try this longer version of initramfs generation. I think the short version is OK for GRUB boot but EFI might need the longer one: sudo /usr/bin/dracut -f /boot/efi/EFI/qubes/initramfs-4.9.56-21.pvops.qubes.x86_64.img 4.9.56-21.pvops.qubes.x86_64 Let me know if that fixes it (or not) so I can update the doc. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
