As per the subject, bsd.rd boots and the installation proceeded as usual. Another laptop saved from ever booting the mess it came preinstalled with. Yay.
Subsequently rebooting results in the following (bsd.sp does the same with different addresses): probing: pc0 mem[632K 475M 255M 208M 137M 150080M] disk: hd0 >> OpenBSD/amd64 BOOTX64 3.46 boot> booting hd0a:/bsd: 12748104+2941960+340000+0+708608 [986153/ I tried booting the 6.5 installer to see if I could find a point between in which it broke but it stops every time after the kernel's penultimate line (between 'scsibus2 at softraid0: 256 targets' and reporting the root device). Interestingly 6.6 also did this once which was seemingly related to having warm-booted immediately prior but it only did it the once whereas 6.5 seems to be consistent. Nevertheless I wasn't paying attention to what the 6.6 installer was doing at the time so I'll look into that some more. I traced the boot process through to loadfile in libsa so I know that it's stuck while reading the ELF symbols (it gets at least as far as the first PROGRESS line after "Now load the symbol sections themselves") but that's probably obvious to whoever knows the boot code. Personally I haven't much clue what should be happening and it's clearly not happening as it should anyway so I don't know what to poke at to get more clues to fall out. The below was extracted by running sendbug -P from within the installed OS (chroot) while running the 6.6 bsd.rd and then doing whatever crazy thing I'm going to need to do to get them onto here. It complained about a lack of /var/db/acpi/* so if they're useful and can be generated from the ramdisk kernel then I can get them too. The dmesg is from the installer's /var.
