Question on when to submit PRs (a reboot hang)

[Chris]

I have what seems to be a mostly stable 6.2 PRERELEASE that I  
couldn't take backward to RELENG_6_1 for reasons I couldn't figure  
out. Unimportant because it's being loaded with data and going to  
test production right now. The "mostly" part is that in cvsupping I  
picked up a nasty reboot problem where "reboot" would stop at Uptime  
and hang about 75% of the time. If the system runs like I've come to  
expect FreeBSD to run over the years, I don't really care plus I'm  
installing a remote Power Tower to overcome such issues next week. On  
6.2 PR, it ran through about 50 reboots without a problem until I  
stupidly updated once more. Yesterday I updated yet another time and  
the frequency of the problem dropped to the point where it didn't do  
it but 1 in 10 intentional reboots. But since I am still seeing it.  
I'm wondering if it's worthwhile putting in a problem report? I  
dislike troubling people if I am the only one who's going to  
experience a problem, especially one which I will soon be able to  
manage it by cycling grouped power inputs (if it even happens again  
now, since I won't be rebooting a production system).

It's AMD64 on an s4882 Tyan.

The question is probably best stated as what is whining and what is  
helping? For all I know it's a timing problem with bios version I'm  
running.
