hello all,
so, for reasons of insanity (or something), i'm trying to get 1.3.2 
working on a 4000/600. This definitely seems like the machine i try to 
get all sorts of outdated unix running on (successfully did 4.3tahoe, 
mostly did 4.3reno, next one on the list is netbsd 1.3.2) 1.3.2 also has 
the distinction of being (one of) the last versions that the CMD qbus 
scsi cards work right under. All the 1.4's and up that ive tried will 
crash hard after talking to a CMD for more than a few seconds, not only 
on the nvax box but also on a ka650. So, to make the long story short, i 
have had all sorts of imaginable troubles! one might think that after 
doing the 4.3tahoe i would be more aware of the issues of making 
something work on a 4600. I went through the 1.3.2 sources, adding 
ka680/690 support where i saaw fit, using as reference both the 
1.5-somthing code and my 4.3t code that does work. As before, i started 
with ka650 code and made what seemed to be the relevant modifications. 
The stray interrupt issue that was by and large solved by borrowing the 
little rei trick from ultrix might or might not be part of my current 
problem, but the rei trick doesnt improve things this time. so, im 
wondering what it is that ive overlooked or blatantly violated! 
i do have the ka680 TM and the 690 addendum, and ive read through the 
most of it multiple times now. 
It _seems_ as if somehow it is not figuring out something important about 
the memory map. It also, as a possibly related thing, couldnt properly 
sort out the console, so i had to fudge it and force it on the gencons 
code.. it took a very frustrated night to figure out why all my printf's 
werent doing anything :-)

here is some output from booting it. i have added massive debugging 
output in a so far vain attempt to figure out whats wrong.. the 
bootblocks didnt work right out of the box either, it took a couple days 
of smacking them around to get them to boot the kernel. i wonder if some
bit of initialization or setup that is supposed to happen in the 
bootblocks is not being done? 

well, here goes. for reference, the system is a vax 4600 with 64MB of 
memory. (originally 192MB but i wondered if there was a 64M limit, so i 
pulled out the other 2 boards. it didnt fix anything)
While i just kept continuing until the final machine check at the end of 
this output, ive been trying to solve the first problem that shows up 
from ubascan. As far as i can tell the error hits right after the 
priority is lowered at the end of a successful use of badaddr (where by 
successful i mean it properly caught the machine check and figured out 
that the address was bad). It successfully pops the saved ipl and 
restores it, but seems to either barf as the result of an interrupt right 
after that, or else die in the next instruction, which is just a mov from 
r3 to r0. I'm suspecting that it's the result of the lowered priority and 
something that was ready to strike just does. 
(the halts from memerr were put in by me, to see what was causing them.. )

thanks in advance for any advice or pointers! 
happy hacking,
isildur
