Hi all


Just found out that squashfs panics when compiled in statically instead of
as a module, when mounting an sqf file. The sequence I did was:


# mkdir /mnt/gaia-ro

# mount /gaiarule.sqf /mnt/gaia-ro -t squashfs -o loop

Maybe it is of importance that the sqf file is located in the initramfs. The
kernel was panicking reliably with different sqf files, on different
hardware upon the mount command, with "unable to handle kernel paging
request". This was on 3.18.5. As soon as I compiled squashfs as a modules,
the problem went away.

If you need further details, please cc me directly, as I unsubscribed from
the list due to not being able to handle the massive load.

What about sharing the actual kernel panic? :-)

Well, I was trying to reproduce it. Upgraded to 3.18.6, built the kernel with static squashfs, and now it doesn't panic anymore.

Guess some fixes for 3.18.6 fixed this too. If somebody really, really cares, I could go through the whole procedure again with 3.18.6, but I guess, as it's gone now, this would be rather academeic.

Bye
Tim
