I did try 3.0.4 and it crashed the same way. I'll try 3.1-rc as you
suggest.

The point is that it worked very well in F14 with 2.6.35 kernels. I was
trying to find out in which kernel exactly the problems began. I couldn't
crash 2.6.36, 2.6.37 and 2.6.38 but, today, 2.6.39-rc1 crashed on me. I
suspect (because there is a small change of behaviour) that the problem
appears in 2.6.38 even though I haven't crashed it yet. Were there some
changes in battery and PM around 2.6.38 ?

Anyway, I start now to compile 3.1.

Thanks,
