>From: gwes

>Synopsis: 5.8 kernel 1305 fails to boot. Generic 5.8 works
>Category: i386
>Environment:
System : OpenBSD 5.8
Details : OpenBSD 5.8 (GENERIC) #1066: Sun Aug 16 02:33:00
MDT 2015
dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC
Architecture: OpenBSD.i386
Machine : i386
>Description:
uvm fault early in booting process. The traceback looks like
the fault is in ddb? but that is probably an artifact.
The release 5.8 kernel boots & runs.
>How-To-Repeat:
boot snapshots kernel 1305 on a VIA chip i386
>Fix:
not known
config(8) changed since release so attempts to build a debugging
kernel have failed - the new config depends on the new kernel :-(
If there is a repository of snapshots I can search through them
looking for the first one that fails
If it's likely that building config(8) from old sources without
pledge(2) pointed at new .h files would work I can try that.
