I did my weekly patches this afternoon, and this time the system booted up fine. So I'm back to what caused the problems. * Motherboard battery? Quite unlikely, but not 100% certain. Battery replaced anyway. * Hard drive? Somewhat unlikely. Two 4-hour non-destructive disk checks found no issues. System cleaned; cables dis- and re-connected; hard drive removed and put back in; no kinky cables seen. Destructive testing and replacing the hard drive are not options for me at this time. Circumstances suggest such would be over-kill. * Somehow caused by the "dnf upgrade"? I can't assess this. After the second failure (May 25), I backed up all user data, and then upgraded from f24 to f25. I did not see any problems. This afternoon's patches were f25; the failures were f24. So I can no longer test whether f24 patching is at fault. But if it were, I'd be surprised if I were the only person to be hit by it. So my leaning is that it wasn't the patching that caused the problems. * Power supply? Somewhat unlikely. I know of no way to test this. But Tim's analysis and other circumstances suggest it's not worth pursuing this possibility any further. Two questions: 1. Are there any other theories I should consider? 2. Should I submit a bugzilla? (If yes, against what?) thanks, Bill. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
