I've fetched and installed this kernel/bootblocks to our DECstation 3100,
and it seems to work quite well - I've done some compilation (of another
kernel at least) with it, and while it has some problems there are no
new problems that I am aware of.
dmesg doesn't work - probably because the allocation of the msgbuf also
sets maxmem to point below the msgbuf area, so you get 'bad adress' from
/dev/kmem. workaround: "cat /kern/msgbuf".
ktrace gets panic: kmem_malloc: kmem_map too small
after this panic, the machine hangs in the boot sequence, so pressing the
reset button is necessary.
I haven't really done very much with the machine in netbsd - mainly
compiling just to put load on it - so this is all I can contribute for now.
