Kernel/World Upgrade causes Hang

[Damien Fleuriot]

Hey Troy,


I can't speak for the rest of the list but I think we're missing a bit
of information here.

What are you trying to build and boot, 8.1, 8.2pre ?

Are you building a GENERIC kernel ? I notice you're currently using a
custom one.

If you're not, I would suggest trying GENERIC first.

You might want to post your whole boot message if it can be recovered.



Also and in case you don't know, you may quickly test your kernel like so:
nextboot -k yourkernelhere

Next reboot, the host will try yourkernelhere, and on the reboot after
that, revert to your regular kernel.


Other than that, quick things to check:

1/ built world before kernel

2/ built kernel SINGLE THREADED (no -j X to speed it up, which you can
do for the world)

3/ tracked the *correct* version in the cvsup file (I've had this case
where I was running fbsd8 zfs boot, and was building a 7.x kernel by
mistake cause I was tracking releng7 -.- )

4/ retrieved and managed to boot a stock GENERIC kernel from 8.1 or 8.2,
whichever you're tracking
