** Description changed:
- Binary package hint: xserver-xorg-video-openchrome
+ [Impact]
+ System lockup on vt switch or resume from suspend
- The openchrome driver locks up the system when switching VT on Via VX800
- based systems (including the Samsung NC20 I'm using). This was upstream
- bug 321 (http://www.openchrome.org/trac/ticket/321) and was fixed in
- upstream SVN revision 838, which unfortunately Ubuntu hasn't yet
- packaged. Any chance of the package being updated in Lucid, or even just
- that one commit being included? This bug means anyone affected cannot
- switch back to X after switching to another VT without the system
- locking up completely, and this in turn breaks suspend, or rather
- resume, as well.
+ [Development Fix]
+ Fixed in upstream revision r838. Maverick includes up through r916 and natty
through r920.
+
+ [Stable Fix]
+ Backport of r838 (omitting the change to Changelog) has been verified to
build and uploaded to lucid-proposed.
+
+ [Test Case]
+ On affected hardware do a vt switch or suspend/resume cycle. Bug should
repro 100%.
+
+ [Regression Potential]
+ Moderate. There may be some hardware for which a full memcpy worked and
copied registers that aren't copied by this patch, however the severity of such
issues will be less than this bug. Looking through the changelog subsequent to
this fix, there is only one bug I see that this patch could expose - graphical
corruption to the cursor following a suspend for VX855 and VX900; possibly
these two chips aren't functioning post-resume anyway due to this bug (I can't
tell without access to the given hw), so maybe that cosmetic issue is worth the
risk.
+
+ [Original Report]
+ The openchrome driver locks up the system when switching VT on Via VX800
based systems (including the Samsung NC20 I'm using). This was upstream bug 321
(http://www.openchrome.org/trac/ticket/321) and was fixed in upstream SVN
revision 838, which unfortunately Ubuntu hasn't yet packaged. Any chance of the
package being updated in Lucid, or even just that one commit being included?
This bug means anyone affected cannot switch back to X after switching to
another VT without the system locking up completely, and this in turn breaks
suspend, or rather resume, as well.
