As a matter of practicality, given this and other problematic bugs w/ EC2 on
the stock Maverick and Lucid kernels (there are several that range from
annoying to flat-out unreliable or un-(re)-bootable), I had been running my
Maverick-based instances with the Karmic kernels pretty successfully
Auto-closing bugs without reading them because you never got around to
fixing them is an *awesome* QA plan. The bug isn't missing any data :P

Stefan, your workaround would almost be acceptable if this were the only
bug in play. However, for those of us booting Maverick AMIs for PV-
grub, and then using cloud-init to auto-downgrade the kernel to Karmic's
or auto-upgrade to Natty's (because let's face it, so far Lucid and
Maverick have
Anyone have a userland workaround (other than ec2-reboot-instances of own
instance-id, which requires auth keys on the node...) for getting an ec2 node
on these kernels to reboot itself successfully?
Also: note that once we have a release kernel w/ the fix, new Maverick
AMIs will have to go out
This looks very likely to be related upstream:

If you haven't fixed it, then yes, it's still an issue. The bug was
found in Maverick. I don't have the time or inclination to test later
versions of the distribution, but either way you need to fix it in
Maverick, and perhaps look at your other kernel packages to see if they
need fixing as
Stefan: the ~32 vs ~64GB memory issue is very likely orthogonal and has
a separate bug now (bug 667796). This issue is solely about intel_idle
vs certain CPU types under Amazon's EC2 (Xen) environment. m2.4xlarge
in us-east reproduces the crash on boot readily (and also happens to
exhibit the
My experience so far has been that the Lucid kernels do not have this memory
size bug, only the Maverick ones.

I wasn't able to boot on ami-d258acbb on m2.4xlarge. It seemed to come up
without the special kernel options:

What's the method for making the S3 AMIs by the way? When I tried before, I
tried just doing standard ec2-bundle-vol stuff inside of a fixed Maverick, but
my first attempts failed because of the root device not having LABEL=euc-rootfs

Well, I had a hunch this morning that perhaps my test AMI was faulty (perhaps
some stupid issue related to block-device mapping, etc, which varies between
the variations on c1.xlarge), since it wasn't packaged by the same
methods/tools as the official one.
It seems this may be the case.
I tried to look in more detail at the crash this evening, because it's really
causing me a lot of headache now. The most recent time I tried to boot a new
c1.xlarge in us-east-1 this evening, I had to cycle through the
crash/terminate/relaunch cycle 7 times before I got a working instance. I
I forgot to add above: on the E5410 c1.xlarge's that do boot successfully, the
kernel output contains:
Oct 26 07:37:55 ip-10-243-51-207 kernel: [0.210255] intel_idle: MWAIT

Oct 26 07:37:55 ip-10-243-51-207 kernel: [0.210257] intel_idle: does not
run on family 6 model
So far my test instances with one or both of the MWAIT-related kernel flags
have given even worse results than the original: They boot showing intel_idle
disabled on E5410 nodes only, but the (assumed) E5506 nodes just terminate
themselves quickly with no console log output at all (even after
Public bug reported:
The postinst script for Maverick (and probably other releases') kernels

Also, as a temporary workaround, I've found that the kernel postinst
script *does* directly create /var/run/do-not-hibernate when a kernel is
upgraded, so that can be used to determine needs reboot as well for
now.
