Ok, after the generic kernel paniced (lppanic: timeout table full)
I loaded the Oct24 src tar_files and crafted a new kernel config (from
GENERICAHA, SUNL-LAMP and my old ZEN) I'll enclose it at the end.
I config'd, make depended and made this kernel.
I made a new kernel copy floppy using:

	gzcat kcaha-10.fs.gz | dd bs=147456 > /dev/rfd0c

I think that was my next problem and should have spotted it when fsck
/dev/rfd0a barfed but /dev/rfd0c worked fine...
Anyway, I had to strip the new kernel to fit it on that floppy...
When I booted from it, it reset the machine as soon a the new kernel
started running...

I commented out a new non-essentials, made clean, depend and a new
kernel.  Then re-made the floppy with

	gzcat kcaha-10.fs.gz | dd bs=147456 > /dev/rfd0a

and the kernel fitted fine and booted better!

Great.  Time to try modems etc...

To cut a _long_ story short(er), all my old Feb12 binaries worked fine
except nnmaster kept claiming it was being with "nnmaster: invoked
with wrong user privileges" it was as if the set-uid bit was being
ignored.  I suspect some set*uid() call was failing.

Q. is there a document somewhere which lists system calls etc that used
to work in 0.9a but do not in 1.0 ?

More alarming was that MHSnet failed to start.  The error was:


	     NETWORK STARTED Mon Nov 7 07:29:21 PST 1994
	available free space on /var/spool/MHSnet/ is 120634 Kbytes
	==== netstate -ersxC
	94/11/07 07:29:21 netstate: system error -- Could not lock "/var/spool/MHSnet/_state/lock": Invalid argument

The lock file _was_ being created ok, but that error message was the
consistent result.  This is more a problem as I don't have source to
MHSnet - its a binary only commercial app compiled for BSDi.

Q. flock or fcntl semantics changed recently?

I had to re-start with 0.9a to be able to get this message out (MHSnet
is the carrier :-) fortunately this is just a case of disabling the IDE
drive in CMOS.

--sjg

BTW I have DDB in the new kernel, but did not get around to trying lpr
again as I needed to resolve the MHSnet issue or swap back to uucp...
Here is the new config.
