Bug Description

From Yingying:

You can get details from patch description. Basically, on some machines (AFAIK, romley, Lenovo x220, Toshiba Z830 .etc. ) with buggy Bios, the firmware will generate quite lots of fake MCE error msg which confuses users and lead them to believe they are experiencing real hardware errors.

The fix is included in the following upstream patch:

commit 29e9bf1841e4f9df13b4992a716fece7087dd237
Author: Fenghua Yu <email address hidden>
Date: Fri Nov 4 13:31:23 2011 -0700

    x86, mce, therm_throt: Don't report power limit and package level thermal throttle events in mcelog

description: updated

Applied to Precise master-next.

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem (3.0.0-24.40). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

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!

Marking verification-done-oneiric. This patch is a clean cherry-pick and has been released in Precise and Quantal with no reported regressions. This patch is also likely suitable for stable.

tags: added: verification-done-oneiric
removed: verification-needed-oneiric

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
