Sometimes, boot gets no further than EFI framebuffer information. Whenever this occurs, the computer will stop immediately in response to a simple, short press on the power button. The two lines preceding framebuffer information (copy typed from a photograph): staging 0xadc00000 (not copying) tramp 0xbecfe000 PT4 0xbecf5000 Start @ 0xffffffff80389000 ... I can not make the issue consistently reproducible. Originally, it seemed that the minority of boots were bugged. For a while, probably more than a week, the majority of boots were bugged (sometimes five or more successive failures). More recently, again, the minority of boots are bugged. There's a strong sense of randomness, so I can not be certain that e.g. safe mode is a workaround. At least once, boot failed whilst the notebook was un-docked and completely without peripherals. Should I suspect any of the modules indicated below? % cat /boot/loader.conf | grep -v \# | sort | tr -s '\n' acpi_dock_load="YES" acpi_hp_load="YES" aesni_load="YES" autofs_load="YES" beastie_disable="NO" boot_mute="NO" boot_verbose="NO" cpu_microcode_load="YES" cpu_microcode_name="/boot/firmware/intel-ucode.bin" cuse_load="YES" efi_max_resolution="1600x900" geom_eli_load="YES" hw.pci.do_power_nodriver=3 hw.usb.no_boot_wait=0 kern.geom.label.disk_ident.enable="0" kern.geom.label.gptid.enable="0" kern.racct.enable=1 openzfs_load="NO" screen.font="8x16" sysctlbyname_improved_load="YES" sysctlinfo_load="YES" vboxdrv_load="YES" verbose_loading="NO" zfs_load="YES" % HP EliteBook 8570p, probed a few minutes ago: <https://bsd-hardware.info/?probe=d9acb17caf&d=FreeBSD>; GELI encryption: % lsblk ada0 DEVICE MAJ:MIN SIZE TYPE LABEL MOUNT ada0 0:119 932G GPT - - ada0p1 0:121 260M efi gpt/efiboot0 - <FREE> -:- 1.0M - - - ada0p2 0:123 16G freebsd-swap gpt/swap0 SWAP ada0p2.eli 2:52 16G freebsd-swap - SWAP ada0p3 0:125 915G freebsd-zfs gpt/zfs0 <ZFS> ada0p3.eli 0:131 915G - - - <FREE> -:- 708K - - - % Three photographs, the first of which is barely readable (sorry): <https://i.imgur.com/waIVcpt.jpg>; (2022-02-18 21:31) <https://i.imgur.com/kmuZmnV.jpg>; (2022-03-18 15:44) <https://i.imgur.com/at7JBbp.jpg>; (2022-04-17 18:58)
