Karmic Kernel Rebase Report (v2.6.31-rc1)

Mon Jun 29 18:51:42 UTC 2009

We have recently rebased the Karmic kernel to the mainline v2.6.31-rc1
release.  During this a number of changes we made and this email serves
to document and record those changes.  This includes the configuration
changes made.

Two patches were dropped from the Ubuntu delta during the rebase:

 - UHCI USB quirk for resume -- this tries to use the early_resume
   callbacks which are now gone.  It was only enabled for the netbook
   kernels.  Dropped.

 - Mask off garbage in Dell WMI scan code data -- changes are now fully
   upstream.  Dropped.

Also during post rebase testing a number of issues were uncovered.
Firstly two staging drivers were disabled as they do not compile:

 - disable staging driver CONFIG_VT6655
 - disable staging driver CONFIG_STLC45XX

A new I2C interface was disabled, note that this was a new driver
and does not have any users currently:

 - disable I2C_DESIGNWARE does not compile

Several ubuntu/ drivers have been disabled as they no longer compile and
will need updating:

 - CONFIG_LENOVO_SL_LAPTOP needs update
 - LIRC I2C needs update
 - ndiswrapper needs update

Several others required fixes to get compiling and will need testing:

 - fix DRDB to use updates accessors
 - fix compcache to use updates accessors

A couple of drivers were disabled for specific architectures only due to
compilation failures:

 - disable CONFIG_FB_UDL for arm
 - disable CONFIG_TLSUP for lpia

The kernel is now producing scsi header files which are also carried
by linux-libc-dev causing archive inconsistancy.  We have disabled the
headers in the kernel until this is resolved:

 - disable adding scsi headers to linux-libc-dev

Finally the kernel configs were updated.  Generally we take the default
unless the option sounds useful, unless the option may be modular when
we will take that option.  The full list of options and their values are
at the foot of this email.

This kernel was uploaded as 2.6.31-1.13.
