Yes, vge(4) and ums(4) wasn't agressively edited recently,
so the breakage is somewhere else. Probably you need to
make a binary search to find the commit that caused the problem.

1) Divide the breakage timeframe by two, to determine the middle.
   (For example 26 Jan - working, 31 Jan - not working. Then
   the middle would be 28 Jan.)
2) Update your sources to the middle.
3) Check whether problem is present?
   Goto 1).

You loop in this cycle until you come to a small timeframe
with a few commits. Then you either determine which one is
problematic logically, or try to apply them one by one. Once
you habe found the problematic commit, you contact its author.

Oh, I see. I know what binary search is, I just thought
I needed to look for some binaries :-) Thanks, I'll try

But first, I want to look through recent commit messages.
While FreshSource is still kind of beta, I wonder what you
usually use to do it. Mailing list? Some tool?

I mirror the whole CVS repo using /usr/share/examples/cvsup/cvs-supfile,
thus I just read /home/ncvs/CVSROOT-src/commitlogs/.

I am pretty sure its the pci commits made by [EMAIL PROTECTED] 
yesterday. It broke all my nForce chipset based boxes.  Try cvsup'ing 
to jan 29th as his commit was on the 30th.

Recent MFC's causing trouble with network and mouse

2006-01-30 Thread Andrew Pantyukhin
I upgraded my world and kernel from about a week's
old state to today's source and network (vge) and
mouse (ums) stopped working. vge0 has a formerly
usual trouble of link state going up and down, while
ums0 doesn't move or feel its buttons (tried moused
and xorg).

Had a look at cvs, didn't see anything suspicious
about vge and ums in particular :-( This is about time
I learnt how to live with several kernels at hand...
