Ok. The alternative would be to find a way to make 7.5 efifb work on my laptop.
The version of efifb from 7.4 works (that is how I installed 7.4 in the first
place), unlike 7.5 efifb.
I'd just like to add that it efifb might not even be the reason for system
hang. I noticed these lines in the output from 7.5 bsd.upgrade I got when I
entered `verbose` at the UKC prompt and exited UKC:
uhub0: device problem, disabling port 2
uhub0: device problem, disabling port 3
uhub0: device problem, disabling port 5
uhub0: device problem, disabling port 6
on my working 7.4 system, I have
uhub0 at usb0 configuration 1 interface 0 "AMD xHCI root hub" rev \
3.00/1.00 addr 1
and later
urtwn0 at uhub0 port 2 configuration 1 interface 0 "Realtek 802.11n \
NIC" rev 2.00/0.00 addr 2
urtwn0: MAC/BB RTL8188EU, RF 6052 1T1R, address <snip>
uhidev0 at uhub0 port 3 configuration 1 interface 0 "SiGmaMicro USB \
Optical Mouse" rev 1.10/1.10 addr 3
uhidev0: iclass 3/1
ums0 at uhidev0: 3 buttons, Z dir
wsmouse2 at ums0 mux 0
uvideo0 at uhub0 port 5 configuration 1 interface 0 "Sonix Technology \
Co., Ltd. Integrated Camera" rev 2.00/0.28 addr 4
video0 at uvideo0
ugen0 at uhub0 port 6 "Atheros Communications product 0xe300" rev \
2.01/0.01 addr 5
so the devices which have a "problem" are all devices connected to USB ports;
or rather, the USB hub itself?
Are there any regressions in the AMD xHCI hub code?
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.
