Here is the ticket where I tried to document the issue i saw: http://shr-project.org/trac/ticket/2103 Hi, it seems that thanks to your mail we have discovered resume problems on 2.6.39 kernels! I tried rmmod ar6000 and i cant reproduce my resume issues anymore! I had running my dial script over night. Freerunner now shows 333 succesful resumes, while it used to fail after 30 resumes before. So please if you are using 2.6.39 kernel edit /etc/modules, remove or comment out line with ar6000, reboot and report if your resume issues are gone. Regards Radek ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community Confirm the removal of that module make the responses of QtMoko for suspend much quicker on my phone. Within my investigation I recognized the qpe process was hanging in disk-sleep state. If that module is included in newer version of Linux kernel it would be probably helpful to look for the changes made. Do we miss only WiFi functionality once the module is removed? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi Radek, all, Hi, it seems that thanks to your mail we have discovered resume problems on 2.6.39 kernels! I tried rmmod ar6000 and i cant reproduce my resume issues anymore! I had running my dial script over night. Freerunner now shows 333 succesful resumes, while it used to fail after 30 resumes before. So please if you are using 2.6.39 kernel edit /etc/modules, remove or comment out line with ar6000, reboot and report if your resume issues are gone. I've been using 2.6.39 with ar6000 commented in /etc/modules in the last week and I've not encountered the resume so far. Editing /etc/modules I noticed that snd-soc-neo1973-wm8753 is repeated three times. Is it the right behaviour? Thank you very much! By the way, gnuchess does not seem to work on this last QtMoko release. Is this a my problem or is it a common one? I've a suggestion for you developers: in the scripts menu (top left icon in the mail menu) it would be great if the script could be return some kind of feedback. For example, each category (such as GPS standby) should present a slide button with the two (or more) possible values (checked against the script behind, if possible). Indeed, it should be something similar to neocontrol... Sorry for proposing instead of coding, but my lack of knowledge is too big :-( Regards Radek Cheers, Giacomo -- ## giacomo 'giotti' mariani gpg --keyserver pool.sks-keyservers.net --recv-key 0x99bfa859 O ASCII ribbon campaign: stop HTML mail www.asciiribbon.org ## ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I've been using 2.6.39 with ar6000 commented in /etc/modules in the last week and I've not encountered the resume so far. Hi, well it's quite stable, but not rock stable, at least not for me :( I had encountered problem that the phone wouldnt wake with POWER button. So i tried call from another phone. The screen turned on, but was unresponsive. I tried connecting USB, but this did not work too. Editing /etc/modules I noticed that snd-soc-neo1973-wm8753 is repeated three times. Is it the right behaviour? No. It needs to be there only once. I messed it in the rootfs howto while trying to figure list of modules needed. It shouldnt hurt, but once is enough. Fixed this in git now. By the way, gnuchess does not seem to work on this last QtMoko release. Is this a my problem or is it a common one? Hmm maybe i can take a look.

Indeed, it should be something similar to neocontrol... These are just shell scripts. But yes, with GUI helper tool they could work like this. I implemented tool for showing QT message boxes already here: https://github.com/radekp/qtmoko/tree/master/src/tools/qui maybe extending this with sliders could work. Sorry for proposing instead of coding, but my lack of knowledge is too big :-( No problem :) BR Radek ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I haven't upgraded from v55 to v58 yet, mostly because of the unreliable suspend issue, but I shall certainly do so soon! Thanks again for your continued work.

hi radek, thank for digging in so deep to find the bug. If I remove the ar6000 does that also mean that I will not be able to use wifi (that would be my guess)? and as an off topic question: if I remove btusb and bluetooth (as I am not using bluetooth at all) would this somehow interfere with qtmoko (eg are those modules expected to be present somewhere else?) best regards and as always: many thanks to you and the extended qtmoko development crew for keeping the GTA02 alive!!! robin ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Yes Maybe it would be possible to use before-suspend.sh and after-resume.sh scripts to rmmod ar6000 and modprobe ar6000 + rfkill unblock wifi. This way wifi should work as before. But I hope we can find proper kernel fix for this. and as an off topic question: if I remove btusb and bluetooth (as I am not using bluetooth at all) would this somehow interfere with qtmoko (eg are those modules expected to be present somewhere else?) It can, i saw some errors during boot when bluetooth was not working. Maybe you would have to disable bluetooth service too to make it working. But i am not sure if it's worth the trouble. Bluetooth is by default off anyways so it should not eat your battery or CPU. best regards and as always: many thanks to you and the extended qtmoko development crew for keeping the GTA02 alive!!! Thanks :) I am also happy that things are moving on. Regards Radek ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

After I took apart my phone, reseated the wifi-board, put it back together, and replaced the two screws which I unsrcewed years ago, I didn't have a single resume (or rather suspend) problem in the last 6 weeks. The imminent problem why the kernel does not suspend again, is that in the kernel there is some handler registered which calls a function off mmc, when going into supend. But the function doesn't return (as it can't communicate with the ar6000?). So it just sits there. This sounds like a good explanation (although i am not kernel dev). Thanks!
