Hi Roxana,

> Shouldn't this be applied to jammy:linux?

No, because jammy:linux does not have the commit that introduces the
issue, namely:

commit c59a1f106f5cd4843c097069ff1bb2ad72103a67
Author: Like Xu <like.xu at linux.intel.com>
Date:   Mon Apr 11 18:19:36 2022 +0800
Subject: KVM: x86/pmu: Add IA32_PEBS_ENABLE MSR emulation for extended PEBS
Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c59a1f106f5cd4843c097069ff1bb2ad72103a67

Which was introduced in 6.0.

Please only apply the patch on Mantic, as requested.

Thanks,
Matthew
