Actually, I do not know :-( Ubuntu devs have not fixed this problem in Ubuntu 3.2 kernel. But these commits in mainline kernel looks related: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=9b04f350057863d1fad1ba071e09362a1da3503e https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=5f2d04f1f9b52604fca6ee08a77972c0df67e082 https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=d851c12b60471188e15e5c8405b289073e8dd025 https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=7f92d334ba19a0d8e96f8f8f092219553367d921 https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=ee9a8f7ab2edf801b8b514c310455c94acc232f6 https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=38d523e2948162776903349c89d65f7b9370dadb https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=fa1e492aa3cbafba9f8fc6d05e5b08a3091daf4a https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=05ab86c55683410593720003442dde629782aaac https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=9cb3a50c5f63ed745702972f66eaee8767659acd https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=b44108dbdbaa07c609bb5755e8dd6c2035236251 However I'm not sure whether they all are required or sufficient to fix everything correctly. -- Best regards, Yura -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
