Not sure to be honest. Just copied Fedora kernel config file and built with that. Will check. > Bojan, this is with Intel drivers, right? Correct. But note that I had similar trouble on a box that has radeon graphics. Essentially, if I pass nomodeset to the kernel, I can hibernate thaw 100+ times with no issues (after all these cycles, the box is healthy, runs programs with no trouble etc.). > I'm CC'ing Keith which might > be able to give some clues how to debug KMS related hibernate/thaw > issues. I am already on intel-gfx list where I asked the same questions, got some suggestions and eventually opened a bug to track the issue. My last message to that list was that I think the problem may be in common KMS code, given I get similar touble with intel and radeon graphics, 32 and 64 bit machines and with or without my patch. -- Bojan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
