Subject: panic when booting on a machine with >= 4 GiB of RAM
Date: Sat, 17 Dec 2011 12:09:47 +0100
Package: kfreebsd-image-9.0-0-686
Version: 9.0~svn228246-1
Severity: important

kfreebsd-image-9.0-0-686 (and most likely all IA32 flavours that don't use PAE)
panics when booting on a machine with 4 GiB of RAM (or more).

Possible ways out of this:

- Enable PAE for all flavours. There are major drawbacks, see:
  http://www.freebsd.org/doc/handbook/kernelconfig-config.html

- Add additional flavours (which ones? 686, 686-smp ... ? and then which
  ones to provide with D-I?)

- Fail gracefuly and prompt user to either remove RAM or use AMD64 version

Please comment!

That's what we're doing on Linux and that seems the best compromise. On
Linux there are many different kernel flavors where it is being worked
on to reduce their amount. I propose -486 for older PCs and 686-pae for
newer PCs. See [1] on more discussion about the minimal required processor.

I am not sure if FreeBSD has drawbacks to use a SMP flavored kernel on a
traditional legacy system with one CPU only. If yes there perhaps should
be a -smp version for each too.

Generally it seems an upstream bug to me though if the kernel crashes on
such a system. Regarding D-I I guess there is no easy way to tell in
advance whether the system needs a PAE kernel or not, and the fact the
wrong choice crashes does not make it any more easy to choose a kernel.

Is it really safe to assume every system with more than 4G RAM supports
the long mode for sure?

It seems that this problem only happens when mfsroot is being used.
Otherwise the extra RAM is safely discarded.

Also, it is reproducible on FreeBSD as well, so I've forwarded it to
upstream (http://www.freebsd.org/cgi/query-pr.cgi?pr=163410)

clone 652448 -1
severity -1 wishlist
retitle -1 PAE support
thanks

Hi Arno,

I'm sorry, this is my fault but when I read your reply I notice I
actually lumped together two different issues:

#1- An important usability bug: kernel panics instead of just
discarding unusable RAM.

#2- Lack of PAE feature which would allow using all the available RAM
instead of discarding some.

I'm cloning this bug so we can have separate discussion about the
benefits of enabling PAE without cluttering the panic bug with
irrelevant information.

Hi,

I am reassigning these orphan bugs (no maintainer, their package was
removed from the archive) to the closest existing packages that I
could find.

Please make sure that they are still valid, that they are now assigned
to the correct package.

Cheers.

The kfreebsd-image-686 one is a meta-package, I'm reassigning those.
