I don't have a n450 H/W on hand, so really thanks if you can try in your n450 platform 12543 3 ke.yu 2011-03-13 20:25:01 +0000 I can reproduce it in a borrowed netbook, so I will continue debugging it in real H/W 12555 4 ke.yu 2011-03-14 00:31:38 +0000 I tried both approaches (disable rootless X, upgrade xserver-xorg-input-synaptics), neither works. so it must be something else wrong 12639 5 dvhart 2011-03-15 10:17:43 +0000 Trying Tom's solution to Bug 738 to see if that works here as well. 12657 6 dvhart 2011-03-15 17:24:10 +0000 The fix to Bug 738 doesn't work here. However, after fixing Bug 869, I no longer see matchbox-panel segfault. I'd like to understand root cause, and it still seems to repro on Ke's netbook. 12683 7 ke.yu 2011-03-16 01:09:58 +0000 (In reply to comment #6) > The fix to Bug 738 doesn't work here.

Yes, i can still see the segfault after bug 869's fix. It should be another issue. 12684 8 ke.yu 2011-03-16 01:39:30 +0000 I believe this is the same issue with bug 224. If I append the following line to gtk+_2.22.1.bb: FULL_OPTIMIZATION_n450 = "-fexpensive-optimizations -frename-registers -O2 -ggdb -feliminate-unused-debug-types" and recompile gtk+, then this issue will be gone. 12690 9 ke.yu 2011-03-16 02:30:59 +0000 Since I don't have BlackSand box in hand, I will ask QA team's help to see if they can reproduce this issue and also if the FULL_OPTIMIZATION_n450 change can fix this issue. 12709 10 dvhart 2011-03-16 14:33:04 +0000 I've tested two solutions. One applying FULL_OPTIMIZATION just to the n450 gtk+ recipe. The other apply the same change to the tune-atom.conf which should apply to all recipes and all machines derived from atom.conf. They work on the n450 and the netbook (Toshiba NB305). I prefer the global fix, but understand it may be more invasive than we want for 1.0. Sending both the list for review and risk assessment. 12710 11 dvhart 2011-03-16 15:41:55 +0000 Fixed in meta-intel bernard: http://git.pokylinux.org/cgit.cgi/meta-intel/commit/?h=bernard&id=0f633ae9cad8ce759dfa965e2b9aa1fce6c4adb7 And meta-intel master: http://git.pokylinux.org/cgit.cgi/meta-intel/commit/?id=01ded1de3b7034f55e7b695b83ab127df96c157b Yu, can you check to see if you are seeing matchbox-panel still segv on atom-pc, the FULL_OPTIMIZATION_atom-pc is set properly in the core gtk+ recipe. If you see it segv on atom-pc, can you open another bug as this one was specific to the n450 and is now fixed. 12720 12 ke.yu 2011-03-16 18:32:13 +0000 (In reply to comment #11) > Fixed in meta-intel bernard: > > http://git.pokylinux.org/cgit.cgi/meta-intel/commit/?h=bernard&id=0f633ae9cad8ce759dfa965e2b9aa1fce6c4adb7 > > And meta-intel master: > > http://git.pokylinux.org/cgit.cgi/meta-intel/commit/?id=01ded1de3b7034f55e7b695b83ab127df96c157b > > Yu, can you check to see if you are seeing matchbox-panel still segv on > atom-pc, the FULL_OPTIMIZATION_atom-pc is set properly in the core gtk+ recipe. > If you see it segv on atom-pc, can you open another bug as this one was > specific to the n450 and is now fixed. I think your patch fix this issue. I don't observe the segv in atom-pc. 12721 13 ke.yu 2011-03-16 18:32:49 +0000 Fixed by http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=35260008f4094100ba337776a2ba5a2cece0d2c7 12787 14 ke.yu 2011-03-17 20:09:34 +0000 verify it. this issue is fixed.
