>Synopsis: recent RAMDISK_CD kernels fail to boot on some systems
>Category: kernel
>Environment:
System : OpenBSD 5.6
Details : OpenBSD 5.6-current (GENERIC) #317: Wed Sep 10 17:49:59
MDT 2014
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC
Architecture: OpenBSD.i386
Machine : i386
>Description:
-current RAMDISK_CD kernels have been failing to boot on a compaq
pressario. the kernel never even reaches a point where it can panic.
5.5-release works fine, and -current works on another system. i found
a snapshot from 26 Jul that has the problem behaviour. the first dmesg
below shows that -current GENERIC works on the problem system. later
dmesgs show the problem & 'solution'.
>How-To-Repeat:
just boot -current bsd.rd (on the right hardware)
>Fix:
i found a partial (ugly) solution (patch at end, for what its worth)
more details are in the various dmesgs below.

well, i tried to track it down, and found it was in sys/arch/i386/pci. i placed
some printf()s before every bus_space_map() and rebuilt, and found the error
was occuring in a call to piix_init(). more tracing led to pci_intr_fixup.c,
where i placed some more printf()s. strangely, one of them solved the problem
(see string 'DEBUG' in dmesg below).

i rebuilt multiple times, with and without. this one statement seems to be
the particular one to affect it. i deleted the other printf()s, just one
mattered (the one right before the piix_init() call).

just this one statement. one before it and one after it had no effect.
i think i am out of my depth now. there is something more internal going on
(why should printf() fix it?)
