Help: System hang/Lockup using snapshots on Intel i5 NUC?

Why 42? The lists account.

Hi All,

We've been running OpenBSD on a server for several years now and its been
reliable with minimal issues, so I thought I would also like to try it as
a desktop system.

Thus I've been experimenting with an Intel NUC 8i5BEH running OpenBSD
current snapshots and with XFCE as the Windowing system. And it all works
very nicely. So well in fact that I've added an SSD, NFS mounted my old
Linux box and rsynced over my home directory. OpenBSD as my main desktop
system!

For the most part everything has gone well, I have only noticed one
serious issue so far: The complete system hangs intermittently. Which is
naturally a bit of a downer :(.

When this happens the mouse is frozen, the capslock LED on the (USB)
keyboard doesn't light up and the system doesn't respond to ssh. To
recover I have to hold down the power switch to shutoff the system, then
turn it on again, reboot and examine the resulting fsck errors.

I have impression this often occurs when using a Web browser. At first
when I used Iridium, then Chrome, it seemed to happen every few hours.
When I switched to trying Firefox, then the hangs seemed to occur less
often, maybe every day or two. Perhaps I'm doing less browsing because of
the hangs :).

The graphics driver being used is: inteldrm0 at pci0 dev 2 function 0
"Intel Iris Plus Graphics 655" rev 0x01

I can leave the system running, sitting at the xenodm screen, for days
without issue. I've also done a couple of complete memtest86 runs without
error. I've even upgraded to the latest BIOS/firmware version.

I've increased maxproc and maxfiles in sysctl.conf and also set
ddb.panic=0 thinking that the behaviour might change to a panic+reboot
instead of a hang, but this made no difference.

After a hang + reboot there is nothing obvious in the log files.

Any suggestions how to further debug such an issue?

The OpenBSD kernel tells me that there is a serial port / UART (com0 at
isa0 port 0x3f8/8 irq 4: ns16550 ...) but I've taken the NUC to pieces
and I cannot see anything on the board that looks like a serial port
header.

The kernel does log a few of dubious messages at boot time. There are
several instances of "not configured". And there is one occurrence of
"mem address conflict 0xfe010000/0x1000". I don't know if these are
relevant, generally the system seems quite stable. Until it isn't. If you
see what I mean. (See below for a complete set of boot time messages).

I would be grateful for any support in debugging, or even better,
resolving this issue.

Cheers,
Robb.

I've got the same behaviour on my new (second hand) thinkpad x250 laptop.
The problem was from the BIOS. It work perfectly since i've made a factory reset.
This laptop was running Windows before buying it...
But now, all work perfectly.

I found this Intel documentation about a dual serial port header on
the NUCs (and the necessary cable), but I don't know if it applies to
your model:
https://www.intel.com/content/www/us/en/support/articles/000017881/intel-nuc.html

If there's no such header on yours, perhaps that serial port is
remotely accessible, e.g. with IPMI serial-over-LAN or Intel vPro
remote access?

You might try an alternate desktop/window manager such as lxqt or
icewm and see if the problem persists.  When I tried XFCE on my X1
carbon laptop, XFCE was not so nice, though I can't remember the
details at this point.

Re: Help: System hang/Lockup using snapshots on Intel i5 NUC?

You might also try testing that memory on that machine is not faulty.

(I've been struggling with an ongoing onslaught of machines with faulty memory.)

Just to follow up, since sysupgrading to the latest snapshot (on 15.3) I
cannot reproduce this problem. (All packages were updated too.)

Also my tentative test case, which resulted in the same symptoms, also
now functions without issue (fyi: run "vblank_mode=0 glxgears" and drag
the resulting window around wildly being sure to get it to go into/out of
fullscreen by hitting the edge of the desktop).

So now  just have to decide if I continue using Firefox or revert back to
Iridium (or Chrome). Decisions, decisions ... :)

Any ideas what I can or should do about my "dubious" kernel messages?
E.g. "0:31:5: mem address conflict 0xfe010000/0x1000"
What does that "0:31:5:" indicate?

Or the "not configured" messages like these for example:
> "Intel Core GMM" rev 0x00 at pci0 dev 8 function 0 not configured
> "Intel 300 Series Thermal" rev 0x30 at pci0 dev 18 function 0 not configured
> xhci0 at pci0 dev 20 function 0 "Intel 300 Series xHCI" rev 0x30: msi, xHCI 1.10
> usb0 at xhci0: USB revision 3.0
> uhub0 at usb0 configuration 1 interface 0 "Intel xHCI root hub" rev 3.00/1.00 addr 1
> "Intel 300 Series Shared SRAM" rev 0x30 at pci0 dev 20 function 2 not configured
> "Intel 300 Series MEI" rev 0x30 at pci0 dev 22 function 0 not configured
> ahci0 at pci0 dev 23 function 0 "Intel 300 Series AHCI" rev 0x30: msi, AHCI 1.3.1
> ahci0: port 2: 6.0Gb/s
It seems as if that Intel 300 chip is only partially supported. Maybe
that's not a significant problem? Though I worry a bit about the
"Thermal" message ... suggesting some temperature sensing may not be
working correctly.

The other good news is that the new (old) keyboard is working well :-)
