Please consider applying upstream patches for mtip32xx

[Kent Baxley]

The quantal-lts-backport kernel contains some much-needed updates for the mtip32xx driver, however, Dell has requested that we also apply an additional set of upstream patches, hopefully in time to make the 12.04.2 kernel freeze deadline.

Attached is a zip file with 15 patches, the files have been renamed chronologically, so that they can be applied in order. All apply cleanly, using the ubuntu-precise git repo, lts-backport-quantal branch. All patches are already upstream, in fact, and they are already in the lts-backport-raring branch.

Hopefully this will be straight-forward.

The patches mostly consist of bug fixes, but, there is one that enables a few new devices. Each patch's filename contains description of what it does.

We have a PowerEdge R820 and a T620 to do any verification work.

Since we are just asking for some patches to be reviewed, setting to confirmed.

This bug is awaiting verification that the kernel for Quantal in -proposed solves the problem (3.5.0-24.37). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

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!

[Kent Baxley (kentb)]

Looks good. Tested on a Dell PowerEdge R820 with one of the mtip32xx PCIeSSD devices. No regressions were noted with these new patches.

Thanks!

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.
