Bug description:
  [SRU Justification]

  [Impact]
  Some recent platform seem to have an unstable HPET, which is used to
  calibrate TSC but turns out to mark an actual stable TSC clocksource as
  unstable, and then fallback to that unstable HPET as main clocksource. A
  previous fix was proposed in bug 1840239, which is then observed to hang
  platforms with modern chipsets including Skylake and ApolloLake at early
  boot stage when HPET is disabled.

  [Fix]
  Commit c8c4076723da "x86/timer: Skip PIT initialization on modern chipsets"
  included in v5.3-rc1 to be backported.

  [Test Case]
  Boot with kernel built with this change, and see if it will hang right
  after grub loaded initramfs image.

  [Regression Risk]
  Low. This change detects the hardware that requires explicit PIT
  initialization skip and skip it. For those unaffected systems, they
  remain unaffected.

  == original description =

  After upgrading kernel to linux-image-4.15.0-1061 (proposed), system
  hangs at very beginning of booting, leaving Grub messages "loading..."
  on the console.

Bug description:
  [SRU Justification]

  [Impact]
  Some recent platform seem to have an unstable HPET, which is used to
  calibrate TSC but turns out to mark an actual stable TSC clocksource as
  unstable, and then fallback to that unstable HPET as main clocksource. A
  previous fix was proposed in bug 1840239, which is then observed to hang
  platforms with modern chipsets including Skylake and ApolloLake at early
  boot stage when HPET is disabled.

  [Fix]
  Commit c8c4076723da "x86/timer: Skip PIT initialization on modern chipsets"
  included in v5.3-rc1 to be backported.

  [Test Case]
  Boot with kernel built with this change, and see if it will hang right
  after grub loaded initramfs image.

  [Regression Risk]
  Low. This change detects the hardware that requires explicit PIT
  initialization skip and skip it. For those unaffected systems, they
  remain unaffected.

Bug description:
  [SRU Justification]

  [Impact]
  Some recent platform seem to have an unstable HPET, which is used to
  calibrate TSC but turns out to mark an actual stable TSC clocksource as
  unstable, and then fallback to that unstable HPET as main clocksource. A
  previous fix was proposed in bug 1840239, which is then observed to hang
  platforms with modern chipsets including Skylake and ApolloLake at early
  boot stage when HPET is disabled.

  [Fix]
  Commit c8c4076723da "x86/timer: Skip PIT initialization on modern chipsets"
  included in v5.3-rc1 to be backported.

  [Test Case]
  Boot with kernel built with this change, and see if it will hang right
  after grub loaded initramfs image.

  [Regression Risk]
  Low. This change detects the hardware that requires explicit PIT
  initialization skip and skip it. For those unaffected systems, they
  remain unaffected.

[Kernel-packages] [Bug 1851216] Re: System hangs at early boot

[Ubuntu Kernel Bot]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
disco' to 'verification-done-disco'. If the problem still exists, change
the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days 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!

Bug description:
  [SRU Justification]

  [Impact]
  Some recent platform seem to have an unstable HPET, which is used to
  calibrate TSC but turns out to mark an actual stable TSC clocksource as
  unstable, and then fallback to that unstable HPET as main clocksource. A
  previous fix was proposed in bug 1840239, which is then observed to hang
  platforms with modern chipsets including Skylake and ApolloLake at early
  boot stage when HPET is disabled.

  [Fix]
  Commit c8c4076723da "x86/timer: Skip PIT initialization on modern chipsets"
  included in v5.3-rc1 to be backported.

  [Test Case]
  Boot with kernel built with this change, and see if it will hang right
  after grub loaded initramfs image.

  [Regression Risk]
  Low. This change detects the hardware that requires explicit PIT
  initialization skip and skip it. For those unaffected systems, they
  remain unaffected.

  == original description =

  After upgrading kernel to linux-image-4.15.0-1061 (proposed), system
  hangs at very beginning of booting, leaving Grub messages "loading..."
  on the console.
