I can consistently suspend and resume without issues. In hindsight, kernel 391 was also giving me issues. My wired network would sporadically fail to come up after suspend. No amount of fiddling would restore. Only rebooting. I have not seen that behavior with 388 either. This would suggest an issue with networking / suspend between 388 and 391. Q: If I update, am I going to lose kernel 388? How can I persist that one specific kernel indefinitely and still be able to update the rest of the system?
