I know very little about all this booting stuff, and the information I've b= een able to glean about it from man pages and such is not clear to me. I am OK = with just keeping with my current workaround* until (if?) this is "really" fixed, rather than trying to mess around with stuff I only vaguely understand (if = at all). However, I'm concerned with something about this for the future, even if a "real" fix is made for this current occurrence of what seems to me to be a = more general problem: Am I understanding correctly that this "slop" area must be manually configu= red by the end user in order to prevent buffer overflow at boot time? Is this n= ot a security issue waiting to happen? Or, at the very least, a very non-obvious and very error-prone system maintenance issue (i.e. whenever you get an upgrade sysutils/cpu-microcode port, make sure to remember to once again manually check the size of the "s= lop" area versus the microcode size)? *: "my current workaround" has me up and running with p9; basically removed= the cpu_microload stuff from /boot/loader.conf and ensured that copies of /boot/loader.efi are at /boot/efi/efi/boot/bootx64.efi and /boot/efi/efi/freebsd/loader.efi, as was suggested on the FreeBSD Forums th= read I opened: https://forums.freebsd.org/threads/upgrade-to-15-0-p9-booting-freezes-with-= efi-framebuffer-information.102766/ --=20 You are receiving this mail because: You are the assignee for the bug.=
