** Description changed: + 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 sta...@kernel.org, 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.
