I knew that many of these patches were not causing direct troubles, but since I found that starting from a particular commit I was building non working (from the suspend/resume point of view) kernels, I decided to take this commit as my base and then adding only the patches (i.e. removing the others) that were more important for the standard usage. > Real solution is coming closer in stable-tracking for these problems > hopefully, although right now accel comms is completely broken in there. > ~ But it should be straight in next couple of weeks kind of timeframe. Nice to read... I'll give it a try as soon as I can, and I think it will be my default kernel as soon as the fixes you mentioned will be there! :) -- Treviño's World - Life and Linux http://www.3v1n0.net/ ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support

It's great you found some suspend stability, but on 2.6.24 / stable there is zero doubt it is purely random chance build by build.

Using this reverting list [1] to get a woking stable kernel (image [2]).

Uh, clearly too busy right now. Anyway the _threshold_ seems to be likewise fixed to 0 currently, ie. cannot be changed.

"Working fine" as in accelerometer using applications (I have AccelGame and Doom) work, unlike with the patch (jerkiness). I don't use suspend with my own kernels since resume is always broken - probably because I only flash the self-compiled kernel and don't know how I could easily also copy the compiled modules into use on Neo. 2008/11/6 Alastair Johnson <[EMAIL PROTECTED]>: > Does it need reverting, or do you just need to echo a smaller value to > threshold when you want to use the accels for game control? I installed/flashed back the kernel from testing. It might be the threshold should just be lower. Unfortunately currently it seems that /sys/devices/platform/lis302dl.1/sample_rate is fixed to 100. Ie. if I do echo 10 > /sys/devices/platform/lis302dl.1/sample_rate, it's immediately back to 100 if I cat it. So I really can't test if the lower value would help. Reverting is probably pointless as such, as most probably the whole rework on the accelerometer side has it meanings (like the suggested suspend problems), but I just haven't found another way to get accelerometers working fluently without reverting the patch in question. -Timo ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
