    I just tested it. The kernel does boot up, suspending to ram works
    perfectly, hibernating did also work, but I found an inconsistent lock
    state in dmesg afterwards. System is still fully functional

    May or may not be related, I don't know.

    But the original problem is solved by your patches. Thank you!

    Thanks for that link. Could one of you hint me to some documentation
    about what tip is? I searched a bit, but didn't find it.
