Which is suppose to happen _now_ so they are busy trying to make sure it works without disaster. Either way, I've some ideas on stirring the pot some more so let send an email out. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

[Fwd: Xen performance kernel patches backported to 3.2 for Precise]
We should consider applying these if we go with 3.2 for wheezy. (Or even if we don't.) Ben. Forwarded Message From: Mike McClurg mike.mccl...@citrix.com To: Ubuntu Kernel Team kernel-t...@lists.ubuntu.com Cc: Tim Gardner t...@canonical.com, #XenOrg xen...@citrix.com, Robbie Williamson robbie.william...@canonical.com, Konrad Rzeszutek Wilk konrad.w...@oracle.com Subject: Xen performance kernel patches backported to 3.2 for Precise Date: Wed, 30 Nov 2011 11:38:22 + Hello Kernel Team, I have just created bug report #898112 [1]. This bug is related to a kernel issue which negatively affects Xen performance on Ubuntu 11.04 and later. This issue is caused by the kernel incorrectly reporting the cpufreq capabilities of the CPU to Xen, which prevents the hypervisor from setting the CPU to the maximum frequency scaling. A blog post describing the bug in detail can be found here [2]. The patch series, which has been backported to 3.2 (and I believe 3.0 as well) can be found here [3]. I ask the kernel team to consider including the 3.2 backport of this branch in the Precise kernel, and possibly the Oneiric kernel as well, if this is possible. Please feel free to contact me or Konrad (the patch author) with any questions.
