* Investigate kernel patches that may help boot speed on ARM devices.
* Write monthly public team report.
* Work on Mythbuntu.

== David Sugar (dyfet) ==
=== This Week ===
* A few failed to builds for arm, including busybox
* Changed ARM default apps focus since we are not getting canola in time
* Tried a new canola build on arm
* Struggled with Lucid Dove

=== Future ===
* Learn entire image build process
* More ftb for arm and otherwise as part of lucid package QA
* Get Dove back up with Lucid

== Alexander Sack (asac) ==

=== Lightweight Browser ===
* Finalize Firefox 3.6 packaging and collect early feedback from
community, fix package transition and get package in archive
* build a chromium with thumb2+neon build in PPA for benchmark
* finalize chromium packaging licensing; get first stab uploaded to
NEW queue.
* discuss benchmarking with mozilla
* work on startup benchmark and try a few javascript benchmarks

=== uboot spec ===
* escalate uboot bugs to freescale

=== dove port ===
* various discussions thumb2/breakage with dove

=== Team/Communication ===
* Release Team Meeting
* collect input on Alpha-3 planning and communicate to managers
* work on sprint agenda

=== Other Contributions ===
* discuss uboot
* sponsor/review fontconfig merge
* MIR processing (uboot-imx)
* sponsor/review network-manager, network-manager-applet and modemmanager
* cleanup work items/blueprints for alpha-3
* discuss openoffice and python on arm with doko

== Paul Larson (plars) ==
=== This Week ===
* spent quite a bit of time trying to determine the cause of the hard
hangs we were seeing with dove. Narrowed it down to pybootchartgui, and
eventually python in general. With some, but not all scripts, python
seemed to be triggering it.
* Tested a new build of python - seems to have fixed the hang problem
we were seeing with dove, at least the one that was affecting boot wrt
* Created virtual milestones, inserted entries for the testcases into
iso tracker database.
* These will be available after the hardy .4 testing is concluded
via iso tracker
=== Future ===
* Bringup testing and results posting
* work on suspend/resume tests

== Steve Kowalik (StevenK) ==
=== This Week ===
Attended LCA 2010, in Wellington, New Zealand.

== Tobin Davis ==
== This week ==
* Spent several hours getting alternate image installed on dove and
modified to where I can test for other failures. Python issues kept
locking the system up, nearly halting all progress. Found that same
drive could be booted on imx51, so used it to apply updates and tweak
boot scripts until environment was semi-stabilized.
* Found another program that segfaults on dove but not on imx51.
Reported it as bug #510954
* Posted bug against Lucid on Dove for the way it currently displays
monospace fonts. Trying to type commands in a terminal window is nearly
impossible due to the font display issues. Same drive & image looks
fine on imx51.
* Ran OLVER Lib tests over the weekend on imx51. Two sets of results;
one with OLVER built against Karmic, one with OLVER built against Lucid.

== Future ==
* need to update OLVER tests based on email correspondence received
from LSB Engineer. Some settings were incorrect, plus there are bug
fixes in the test suite that are not in our snapshot.
* daily testing.
* Prepare for PDX Sprint.

== Michael Casadevall ==
* Lost most of last week due to sickness
* Worked on porting likewise to ARM
* Continued investigation of Dove thumb2 issues
* Worked with ericm on testing newer Dove boards for stability
* Got JTAG up and running on Dove Y0/Y1

== Future ==
* Dove stability investigation continues
* Prepare for PDX Sprint

== Minutes ==
* ogra informed the team that after recent work on the iMX51 image
including kernel patches that were back-ported by cooloney, there is a
noticeable boot speed increase.
* gnome-panel crashes still persisted in the images despite work being
done by plars to find the issue. A bug was filed
(https://launchpad.net/bugs/458109) and investigations continue.
* NCommander took up the action item to look into crash issues with
the apport retracer which can be flaky at times. It is believed that the
ARM fakeroot implementation causes this but no more is known at this time.
* Talk drifted to Thumb2 issues again, this time asac reported the
outcome of talks with dmart from ARM. asac explained that there are
three possible area's where Thumb2 could have issues, 1) user space
apps; solution is to work around issues, 2) kernel/toolchain; eliminate
bad instructions, and 3) hardware; fix bad hardware. Of the three we are
seeing on the dove images, the team decided that ideally we would see a
change in hardware but the most likely route would be kernel and
toolchain workarounds.
* vldr instructions continue to be a problem on dove. The only
possible outcomes at the moment are rebuild the archive for generic ARM,
losing all iMX51 performance improvements or find a work-around.
Obviously the latter is preferred but the solution escapes the team at
this time.
* ogra informed the team that uboot is to be dropped this cycle in
favour of continuing with redboot. uboot has proved to be a little too
much to implement for this cycle.
* Discussion moved to meeting schedules again. persia took the action
item to investigate a good time to reschedule the meetings after this cycle.
* Team work items look to be in good shape with the current status
being just above the trend line. There was talk that by the end of the
week they would be in even better shape as both asac and JamieBennett
planned to close multiple items. There is an outstanding issue with the
bootloader spec so asac and ogra took up the action item to sort that out.
* iMX51 kernels were reported to be in good shape with both plars and
GrueMaster indicating that testing had gone well, with plars' new
testing methods contributing. He invited people to help fill in the test
plan at https://wiki.ubuntu.com/ARM/Testing/ArmPairwiseResult
* GrueMaster indicated that he had issues with ubiquity last week but
plars mentioned that more recent images seemed to fix it.
* JamieBennett mentioned that the Canola media player would not be
ready for Lucid but it continues to be an interesting prospect for Lucid+1.
* The fail to build list for ARM looks in great shape at this time.
Thumb2 utilising packages will still need to be reviewed on a
package-by-package basis and asac took up the action to do this.
* ARM images are looking good even though there are still issues with
dove. The team hope to resolve that one way or another very soon.
* ogra asked if bootchart could be removed from the seeds now. plars
and JamieBennett indicated that they would like to see it stay for now
and took up an action item to discuss this later.
* persia has been working with rbelem to get Ubuntu Liquid into shape
with the consensus that they are progressing well and aiming for a
alpha-3 release.
