Ops, I am sorry. But in the bug description which Rafael wrote above there is a link to your original post References: http://lkml.org/lkml/2008/2/23/263 so I thought this was the bug being dealt with here. > However I thought that we are talking about the hang with > ladder governor as the last message on the screen.

I thought that the bug had vanished, but two days ago it happened again in my Vaio. There were a couple of different messages comparing to the picture in the link above, but the last message was exactly the same. And I see that Rafael closed the bug http://bugzilla.kernel.org/show_bug.cgi?id=10117 The hang two days ago was with 2.6.25-rc7-00150-g(can't remember), do you think the bug was fixed since that kernel? I will try to test with the latest git, but I don't have internet access at my house anymore, so I will have to clone the git repository into my pendrive and take it there...
