Re: How do I report a kernel panic occuring on install media?

Thanks. Your email gave me hope.
I thought it would never be possible to run OpenBSD on the hardware.

This is important information. I think it would've been nice to see
something about it on man pages, documentation, download page or
somewhere noticable. I have a feeling there is something but I totally
missed it.

This worked. Gave me a "UKC" prompt.

boot> boot -c
...
UKC> disable acpiec
257 acpiec* disabled
UKC> quit
...

Then it booted like usual to install-upgrade screen.

I don't know how to have a OpenBSD dual booting install so I tried once
and then cancelled and then realized my whole HD was formatted!!! Even
though I cancelled!!

I tried installing to a flash drive and it didn't get detected (probably
due to disabling acpiec). Then tried to install on the install media
itself. It seemed to work.

Wifi wouldn't turn on, so had to connect ethernet cable. Installed file
sets from a mirror (I entered http, [enter], ftp.jaist.ac.jp, enter ...
-x*, -game*, -comp* - in case someone else gets to this thread in
future) since the install media doesn't have the file sets anymore and
has been already formatted for the installation.

It was getting hot when installing file sets. So I pointed a table fan
at it just in case. :)

After installing I rebooted and tried disabling acpiec first and it
worked like before. I quickly got a dmesg and dmesg.boot.

Then I tried booting again and again disabling one by one of these each
time to see what happens:

acpi0: boots
acpitimer: boots into ddb prompt
acpihpet: boots into ddb prompt
acpiac: boots into ddb prompt
acpibat: boots into ddb prompt
acpibtn: boots into ddb prompt
acpicpu: boots into ddb prompt
acpicmos: boots into ddb prompt
acpidock: boots into ddb prompt
acpiec: boots
acpimadt0: boots into ddb prompt
acpimcfg: boots into ddb prompt
acpiprt: boots into ddb prompt
acpisbs: boots into ddb prompt
acpitz: boots into ddb prompt
acpiasus: boots into ddb prompt
acpisony: boots into ddb prompt
acpithinkpad: boots into ddb prompt
acpitoshiba: boots into ddb prompt
acpivideo: boots into ddb prompt
acpivout: boots into ddb prompt
acpipwrres: boots into ddb prompt

For some reason ssh access is not working even though port 22 is open.
I'll try to get the outputs and post it to @bugs. My email is
also having trouble so don't know how soon I can post it.

Will check later.
