Title:
QRT test-kernel-security causes kernel panic on EC2
So after several tests I have replicated this on a 2.6.35-25-virtual
kernel, not the crash is sporadic and does not show up every time.
So the bug is not a regression in the proposed linux-
image-2.6.35-27-virtual 2.6.35-27.48 kernel.

Nikolaus upstream does watch here and track bugs filed in launchpad.
This particular issue arise due to the LSM not providing AppArmor
sufficient information about access on stacked file systems. You can
mostly work around the issue using the alias command
can you try adding the following
Nikolaus,
did you restart apparmor after making the change? The profiles will have to be
reloaded.
sudo /etc/init.d/apparmor restart
if that doesn't work can you attach your profiles

apparmor doesn't work on stacked file system (livecd) -- DHCP/cups/others fail
to start
Nikolaus,
thanks, it looks like you have hit a bug in the alias command, I'll look
into this and see if I can't get something for you to test in the next
couple of days.

Right I messed up the alias order but there is still a bug in alias processing,
that needs to be fixed before this will work. Basically setting
alias /etc - /rofs/etc,
will result in rejections for accesses to /etc/ instead of /rofs/etc/

Martin,
can you elaborate on how this helps, where you notice it, etc.
Also can you reboot with AppArmor enabled and rerun aa-status and attach
its output along with the the kern.log again.
Also can you try,
making symlinks in /etc/apparmor.d/disable/ to the /usr/sbin/mysqld and
Just an update we have Karmic kernels now (see lp bug 418130), also the
alpha6 ami when release should a karmic kernel set as the default. This
should enable testing to proceed.

No I haven't been able to confirm it is a kernel issue yet, though I am
planning on devoting some good time to this bug over the next couple
days.

Importance lowered as there is a function karmic kernel with the Xen
patchset (lpn Bug #418130) that can be used. It is still desirable to
fix this bug as using a pv-ops kernel is desirable in the long run.
This bug is still blocked on obtaining further information from Amazon.
