Hi, Sorry it took some time. I tried the patch with 2.6.39, it does not seem to help as I still observe the crash. I was not gifted with a warning in the logs, though. (I used 2.6.39 because it's a kernel with a quite high rate of bugging on suspend/resume. I had to apply manually one of the chunks of the patch.) Is there a debugging option which would help having more info on the log ? Thanks, Éric Brunet
