Perfect Petr, thanks for your feedback! I'll be out for some weeks, but after that what I'm doing is to split the series in 2 parts: (a) The general fixes, which should be reviewed by subsystem maintainers and even merged individually by them. (b) The proper panic refactor, which includes the notifiers list split, etc. I'll think about what I consider the best solution for the crash_dump required ones, and will try to split in very simple patches to make it easier to review. Cheers, Guilherme
