Meeting Agenda]]


=== ARM Status ===
Q/master: lp1176977 ("XFS instability on armhf under load") - working with
upstream on this one: i already backported a fix that turn the
vmalloc() exhaustion
and fs shutdown to an -ENOSPC error, and this second error seems to be
triggered
by the tiny fs used in these tests (~2GB). Still working to get it
properly fixed.
R/master: lp1171582("[highbank] hvc0 getty causes random hangs") -
the jtag console has a 1-char producer-consumer buffer and if there's no
real hw attached to the board, any subsequent write turn into an
endless loop
waiting for a consumer. The situation is worsened by the fact
that before writing to this register a tty spinlocked is taken, and
any subsequent tentative to pick this spinlock makes the thread hang -
got a confirmation of the problem, some info about the hw, and i'm
working on this.

=== Release Metrics and Incoming Bugs ===
Release metrics and incoming bug data can be reviewed at the following
link:
* http://people.canonical.com/~kernel/reports/kt-meeting.txt

=== Milestone Targeted Work Items ===
The burn down charts have not yet been reset for 13.10, so disregard the
second link posted abovefor now. I'll be cleaning up and adding work
items for 13.10 so that the +upcomingwork link will be more accurate.
Next week I'll have the usual nag table available.

=== Status: Saucy Development Kernel ===
For now, we'll plan on targetting the v3.10 kernel for Saucy but will
strongly re-evaluate a move to v3.11 in the coming months. We've just
rebased Saucy to v3.10-rc2 and are still cleaning up some of the
carnage. I don't anticipate we'll upload until a later -rc which will
hopefully provide more stability.
Importand upcoming dates:
Thurs June 20 - Alpha 1 (opt in)
