Hello Justin and Stuart,

I hope the following may be of help in solving the cause of the crash.

I have experienced a similar type of crash when using X on this machine
for approximately the last 6 weeks. Prior to this, X had been running on
this machine without apparent problems for 12 plus months.

The only browser installed on this machine is lynx(1). My crashes have
been random with no recognised culprit at the time of the crash, which
usually occurred within 10 minutes of invoking startx(1).

fvwm(1) is the only window manager installed on this machine. All my
crashes have required the machine to be powered off to regain control.

This machine's graphics card was identified by it's vendor as a:
  Sapphire Nitro+ RX580 8G GDDR5 Graphics Card 2X HDMI + 2X Display+DVI
  Port.
This machine is connected to it's monitor using a Display Port cable.

This machine has worked and is working without problems from a console,
with and without tmux(1). If multiple consoles are run at the same time
however, when exit(3) is invoked from one of them the time taken to
exit is sometimes longer than 10 seconds. This seems odd to me.

Please find below the contents of this machine's /var/run/dmesg.boot.

Thanks Antoine. I've now got Cups working on my laptop, by setting
socket://. This is not yet working on my Desktop (-current)
although the "printer not found" error no longer appears.

I'm not sure which configuration I should post here - some of the
files in /etc/cups?

It's occurred to me that the problem on the desktop may have
happened because on a couple of occasions recently after an upgrade
I was unable to make the requested deletions (they disappared from
the screen before I could do it). Tomorrow I'll try reinstalling
Cups from scratch in case that fixes it.

Re: Web documentation available offline by default?

[Luke A. Call]

Another option I found helpful once is to use wget to download the
FAQs' content to a local copy (unless that puts too much load on the server),
then have a simple local shell alias to view it with links or w3m.
(At the time, it was a quick way for me, to preserve the content
in case I wanted it while offline, or if things like X weren't working.)
There are probably pros & cons of doing that, vs. CVS -- maybe making a 
CVS copy is actually cleaner & simpler for this, and for updating it.

I can fish out my old wget line for that, if it is of interest and not
considered harmful.

Sometimes it might be the way a particular graphics toolkit "tickles"
the video hardware too.  For instance FVWM uses libxcb for drawing
graphics which means you're likely to be just working with 2D primitives.

Then Firefox with its GTK+ back-end fires off a few RENDER extension
requests to the X server and whoopsie!  Down she goes!

No issues for months running a previous version of OpenBSD or the same
you're running now?

One suggestion I made too was to maybe try setting up a serial console
link… turns out the motherboard makers know how to tease:

> com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo
> com0: probed fifo depth: 0 bytes

That says there is a RS-232 port somewhere… so I had a look at the handbook:
https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/ROG_STRIX_B450-I_GAMING/E14337_ROG_STRIX_B450-I_GAMING_UM_PRINT.pdf

They didn't wire it up to a pin header, which is annoying.

On the video front, I did see this:

The "stub" messages make me wonder if we're hitting some
not-yet-implemented features.  That "failed to retrieve minimum clocks"
has been seen on Linux as well, and there it was related to PCI prefetch
register programming.

The machine you've got isn't much different to what I have at work
actually: Rysen 7 1700 (so previous generation), and a RX550 video card
(POLARIS12, maybe slightly newer?)… the machine is fitted with a RS-232
serial port so I might try a little experiment with a USB stick and see
if I can install OpenBSD 6.6 to USB storage and try to reproduce the crash.

Re: Catastrophic

[Justin Noor]

Thanks for offering to help and sorry for the delay - I got dragged into a
work emergency. I finally managed to SCP my dmesg to a remote machine.

As a refresher I have a 6.6 current machine that crashes when X is running,
and almost instantly when Firefox is running - it runs fine without X. The
machine becomes totally frozen - I have to perform a forced shutdown to
exit this state. The issue appears to be graphics related and is
inconsistent - sometimes it crashes immediately, other times it does not.
There are indeed some "unknown product" messages related to my PCI graphics
card in my dmesg, but I haven't been able to decipher them yet. Those
usually mean the device is not supported, but it is, and I'm sure I have
the correct driver (amdgpu0). Previously I had no issues for months, which
is why I suspected hardware failure. Admittedly I've been lucky with
graphics cards over the years, and don't know much about PCI.

Can you share your configuration?
If it's a network printer, it could be that cups is trying to connect to your
printer using avahi which doesn't work on OpenBSD.  You must make sure you
configure your printer using hostname or IP.

What about having good old plain text obsd-faq.txt
 mirrored in

Or maybe it's there but I could't find it:

Hi Frank,

Maybe it just got deferred for the moment of more elegant (simplified) mandoc
markup frontend editing.  Editing HTML by hand is inconvenient + highly error
prone at the same time as shown in many iterations of missing closing tag and
other numerous errors hidden by the viewing pagers (error covering browsers).

Editing HTML by hand should be reserved for fine tuning and maintenance of an
export filter of a document specific authoring and editing convenient markup.

Using mandoc for the purpose of system and accompanying documentation is "the
best" current practice solution, it was designed for/in this specific domain.

Lightweight markup formats are an enabler for document authoring and editing,
as demonstrated by the largest online collaborative systems (encyclopaedias).

At the same time, lightweight markup can optionally contain semantic (mandoc)
markup and export cleanly to HTML, as mandoc can export to lightweight markup
and HTML and other preformated (typeset) document output formats.  An missing
at the time system has never been an impediment to outstanding, and excelling
work in the maintenance and preparation of the documentation as if it's here.

Kind regards,

CUPS sudden refuses to print after previously working fine

[Anthony Campbell]

 I have a networked Brother-HL5350DN printer which has worked fine
 with CUPS for over a year. Two days ago it suddenly refused to
 print on my desktop running -current I reconfigured the printer
 several times without effect.

I then set up CUPS on a laptop running -release. It also failed. In
both cases the printer appears on screen and I can queue jobs for
printing as normal but they don't print. The printer itself is
working normally from my wife's computer. I cam ping the printer
without difficulty.

I turned on debug and found this:
[Job 30] Unable to locate printer \"BRN001BA92DB44A\"

I'm mystified. Whenever I've set up the printer in CUPS previously
it has always worked. The only clue I found was on Arch Linux where
they talk about needing to set up avahi jn such cases, but I don't
know if that is relevant here.

Any ideas gratefully received.


Anthony
