Seems like I'm running into a serious problem upgrading my 5.1 machine to the latest level:
The symptoms: I did an upgrade (cvsup) then went through the usual build/install cycle (see below).
When I boot the new kernel everything runs straight up to
the moment when I start X-Windows. When starting X as a normal user I
end up with a "db"-prompt (debugger?) - from there I can only "reset" :-(. (for details about the messages see below) When starting X as root the screen goes blank and after some seconds the box reboots.
As far as building & installing is concerned I did everything as per chapter 21 of "the handbook", including installing binaries (userland) in single-user mode, running mergemaster etc.etc i.e.
make buildworld; make buildkernel; make installkernel shutdown -r fsck -p mount -u / mount -a -t ufs swapon -a cd /usr/src make installworld
When booting the old kernel (kernel.old) everything is fine again -
so assume the problem is with the kernel itself. The "old" kernel is the one that has been installed when installing 5.1 from the CD.
I also did a "diff" between the GENERIC file that came with the original installation and the one that was installed using cvsup (i.e. the one used in the fresh build) - no difference except the version string.
I tried configuring "device mgadrm" into the new kernel (this wasn't there in the the original GENERIC though) - to no extent - same crash.
Also: I've no indication about a problem in either /var/log/messages or the X-log - seems the box crashes before being able to write anything to the log.
Has anybody else seen this? What can I do against it?
Since I don't want to post exessive logs in the first place, here's what I've got:
Asus CUSL2-mobo 512MB RAM 2 IDE HDs (80, 60GB) Matrox G400 graphics
When upgrading I went from the version that comes on the 5.1-CD to the latest one available via cvsup (the "UPDATING" file has an entry of 2003-09-28)
Please let me know if you need any additional details.
Thanks much in advance for your help, -ewald

Here's the output from "db" which is where I end in when I start X:
(BTW - does anybody know a way how to capture this output besides "writing it down"?)
