[Bug 795717] Re: 32bit rhel and centos 5.(5|6) hangs on boot on natty

[Herton R. Krzesinski]

@nutznboltz: the natty kernel with the fix readded is available in
-proposed now (2.6.38-13.52).

Please test the kernel from -proposed and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be
dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  32bit rhel and centos 5.(5|6) hangs on boot on natty

Status in “linux” package in Ubuntu:
  Fix Released
Status in “qemu-kvm” package in Ubuntu:
  Invalid
Status in “linux” source package in Natty:
  Fix Committed
Status in “qemu-kvm” source package in Natty:
  Invalid

Bug description:
  SRU Justification:

  Impact: An upstream change in the kvm code in 2.6.37 causes
  regressions running 32bit guest under 11.04 (Natty) KVM.

  Fix: Cherry-picking a single upstream patch (which went into 2.6.39)
  fixes the issue.

  Testcase: Booting 32bit rhel and centos 5.(5|6) guests under Natty
  used to hang, but has been verified to succeed with a test kernel
  including the upstream patch.

  Binary package hint: qemu-kvm

  I have several guest images that ran fine under 10.10, RHEL and or
  CENTOS 5.5 and 5.6 x86 all hang either from ISO or from disk image on
  boot, some times it will find the LVM and mount and crash sometimes it
  will crash after NASH starts.
