linux-image-2.6.35-25-server won't shutdown or reboot when running as xen domU

[halfgaar]

Binary package hint: linux-image-2.6.35-25-server

Exactly like #695012, but with a newer kernel version, and for Ubuntu Maverick (10.10)

When installing Maverick (10.10) as a domU in a Xen virtualized environment with vcpus > 1, it won't shutdown or restart. Upon shutdown It just says forever:

 * Will now halt
[ 10.811099] System halted.

DomU is using 100% CPU in the meantime.

Patch which is supposed to cause this:

http://kerneltrap.org/mailarchive/linux-kernel/2010/11/19/4648631

I'm not 100% sure, but if I remember correctly, my DomU's with 2.6.35-22-server work fine. It's just that I don't remember if I've always used them with more than 1 vcpu.

halfgaar, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it.

Please let us know your results. Thanks in advance.
