I've also had the same when suspending to disk on the console, so this does not seem related to i915 or Xorg. I thought I would bisect this trying 2.6.27 - 2.6.28, I suspect that 2.6.27 was still okay - but the problem is that I'm now using EXT4 for my root file-system, and I get a panic on boot with "cannot handle large files.... CONFIG_LSF is not set" or something like this. It seems this option is to handle TB sized files, and I only have a 200GB laptop drive. Can I enable the option (though it seems obviously wrong to me), or is going back so far into EXT4 history a bad idea? Niel
