My 100% guess is that you have a machine that's very dependent upon
ACPI, and the install kernel's ACPI support is very minimal, or
has a funny UEFI system. Or a funny BIOS. Some machines work better
as UEFI, some work better running BIOS. A firmware upgrade may
change that (which could suck).

There are other ways, though...

First, I would verify that the 7.5 kernel boots -- copy it to /bsd75,
for example, then "boot bsd75 -s" (the -s is so it doesn't try to go
multi-user with a mixed new kernel/old userland/packages). If that
seems happy, just do a "remote upgrade", using the "Manual Upgrade
(without the install kernel)" process in
https://www.openbsd.org/faq/upgrade75.html.
