Present: Jim, Kim, Mitch, cjb, c_scott, dilinger, dwmw2, Jordan,
Bernie, m_stone, ...
Topic - focused bug triage with particular emphasis on update.1
delivery, then a discussion of vserver and containment issues.
1396 Update.2 Ebook reader should suspend on idleness
Fixed - but needs to be turned on with the policy files
(Touch a file in the filesystem to turn it on.)
- CJB to turn it on, but only for >= C2 systems.
2679 Update.2 Suspend on idle
- cjb to work on this after other ones that are lower-level
- cjb to supply a list of those other ones
2765 Update.1 EC needs programmable delay to turn off DCON chip (XM-killjoy)
- Reassigned to cjb to try doing it in OHM
- We need to do tinderbox tests to determine the power impact
- jg to check up on that tomorrow
1752 Update.2 USB wireless suspend/resume failure at setup phase
- Closed
2353 Update.2 Hang (USB, DCON) going to suspend
- Close as fixed
2401 Update.2 rsmith Wakeup event is repeated continuously (EC and kernel)
- The recipe given by MitchCharity has been reproduced by Mitch Bradley
- Not a show-stopper because the system recovers if you press the
button again
- We don't want spin firmware for Update.1 unless a more serious
problem surfaces
2699 Update.1 kernel usb storage does not write dirty blocks properly
while unmounting
- Important - reproducible, serious, probably fix-able
- dilinger to work on with high priority
2833 Update.2 camera fails in os547
- Works now because we reverted to an older gstreamer
- Left open but deferred to Future to see what happens upstream with
gstreamer and kernel
3470 rsmith No indication of low battery; laptop just shut down - No
definite recipe for reproducing
3610 rsmith Mystery shutdown without red warning LED - No definite
recipe for reproducing
4370 hardware No indication of low battery, laptop just shut down
- kim to collect all similar bugs
3579 Wireless hang after setconfig
- Closed, fixed by hardware changes
3978 Journal getting blank
- Might be fixed as of build 616
- Expecting to land with datastore fixes
4032 Touchpad not that easy to use
Longstanding bug - could be a kernel locking issue, could be
resistive interference
- Would be nice to be able to turn off the resistive area
- jg to file new tickets for specific improvement opportunities
1407 Force recalibration when power situation changes
- Move to update.1 and make it a blocker
4184 JFFS2 Dirent Anomaly
- We have several workarounds for this, and a solid fix if we can
remove vserver
4223 hardware Spinlock lockup on resume (LOOK) {This is the potential
memory corruption thing}
- Retest without vserver
4431 WLAN disappears after some number of suspend/resumes
- Closed
4466 EC hang after large number of suspend/resumes (MP Start)
- Low priority now
4217 Wireless/USB kernel panic on resume
- Closed as duplicate
4401 rsmith Sugar battery capacity does not update (There is a patch for
this; perhaps downgrade)
- Reassign to kim for testing
4439 rsmith HAL doesn't understand our battery class anymore. (Patch
available, also needs EC fix)
Fix apparently available, needs testing
- Can test latest stable kernel, but also awaiting new EC bits
4490 pdflush takes 80% cpu on 622
- Dup of 4184
Summary of Containment Issues:
* With vserver, we have an existing system implementation, but the
activities
are only partially converted and have not been adequately tested.
* The vserver kernel patch is unstable. The systems team
unanimously believes
that it can't be fixed quickly.
* The UID-based containment scheme has been designed but not yet
implemented.
The system-level implementation has no obvious roadblocks and thus
might not
take too long, but the activity conversion issue still remains.
* We lack adequate resources for converting and testing activities.
* The datastore needs modification to work across the isolation barrier.
* c_scott and Ivan believe that, if we fail to ship filesystem
isolation for
Update.1, it won't be economical ever to do so (because it will break
backwards compatibility).
