Bug Description

SRU Justication:

Impact: On powerpc, the cardbus code needs to run through fixup code, otherwise the kernel will crash with inserted cards.

Fix: The patch, backported from upstream, will create a fixup function which is doing nothing on all architectures but powerpc. And for powerpc
it will call the required fixup code. For Lucid this has been forwarded to <email address hidden>, but the 2.6.31.y support ended now.

Testcase: See below

Binary package hint: linux-image-2.6.31-14-powerpc

Using PPC Karmic of 2009-10-19, on inserting a PCCard (a USB 2.0 device), the kernel Oops is observed. This may be related to https://bugs.launchpad.net/bugs/421940, which is another failure of the PCCard sub-system on PPC.

A patch was published 2009-12-09 by Benjamin Herrenschmidt <email address hidden> "[PATCH] cardbus: Add a fixup hook and fix powerpc" that fixes this problem.

The patch is attached. It applies with offset against 2.6.31 kernels, and cleanly against 2.6.32.

Is this patch going to be included on regular Ubuntu updates or do I have to apply manually?

If is not going to be included on Ubuntu updates, how do I apply this patch? I'm using kernel 2.6.31.

Thanks.

The fix currently is only available in our pre-proposed PPA (https://launchpad.net/~kernel-ppa/+archive/pre-proposed). It will be included in the next kernel going to proposed, but it waits on the current proposed kernel being moved to updates.

There appears to be no installable package for the architecture (ppc) that this bugs affects, which makes testing the fix less easy. Is this correct?

Seems the packages for Karmic need archive action to be released. Thanks for the
pointer.
