Could you please set ddb.panic to 1?

It's hard to figure out what's wrong in your reports because as soon as
your machine tries to reboot it panics, panics and panics again.  So we
can't tell what is the first (real) problem.

And please stop cross posting.  bugs@ is enough for such problems :)

Thanks,
Martin

Catch the second one kernel panic.

The output is the same, but on another kernel.  Hope this helps.

Sorry but can you give more context?  How does this happen, why do
you need to do?  What is the output of 'ps', what is your dmesg?  What
is your hostname.runX ?

See https://www.openbsd.org/report.html for more informations about how
to report a problem.

Sadly it doesn't.  It only creates frustration from both sides.  Please

Hello Martin,

Please let me know if need more information about machine and test
conditions.

$cat /etc/hostname.run0

dhcp lladdr xa:xb:xc:xx:xy:xz bssid ya:yb:yc:yx:yy:yz nwid <BSSID> wpa
wpakey <KEY> wpaprotos wpa2

I've copied the explanation from my previous post.

"From time to time I receive Kernel Panic on OpenBSD 6.2 amd64 when run0
driver for RT3070 based device is attached to the Lenovo X220 laptop
during boot.
It appears just after file system is mounted. Next boot I receive that
file system was not properly unmounted.
But after FS checking is completed the same run0 device usually works as
expected.  

The same thing when I connected RT3070 device to the fully booted
OpenBSD6.2 amd64. Three times out of ten I got kernel panic issue.

I have tested two RT3070 adapters on other systems. Both works smoothly.
But on 6.2 amd64 each of them produces panic issue with the same
probability."

Here is DDB output.

Re: Kernel Panic on 6.2 amd64 when run0 RT3070 based device is attached during boot

Denis Lapshin-2
In reply to this post by Martin Pieuchot
I installed OpenBSD 6.3amd64 from latest snapshot two days ago. The
panic is a bit different with run(4) driver and RT3070 USB dongle than
on 6.3amd64. The testing machine is a bit different and its dmesg is
listed after panic info.

during boot:

...
machdep.allowaperture: 0 -> 2
starting network
run0: no link ..... got link
run0: bfdesc: ERR|HUP|NVAL
run0 detached

Re: Kernel Panic on 6.2 amd64 when run0 RT3070 based device is attached during boot

It seems pretty strange to me that your run device attaches
via ohci (USB 1 controller) and not via ehci (USB 2 controller).

Is there a way to make it show up on ehci, perhaps via BIOS settings,
or by plugging it into a different USB port?

Regardless, maybe run(4) via ohci could work, but it definitely
should not panic the kernel.

This panic looks like we are missing a timeout_del() somewhere?

No worries, there's enough information in the traces above.

Re: Kernel Panic on 6.2 amd64 when run0 RT3070 based device is attached during boot

Denis Lapshin-2
In reply to this post by Stefan Sperling-5
It seems ohci is USB 1.1 keyboard serving controller. The panic about it
showed by ddb{}. I obliged to set in BIOS both 1.1 and 2.0 modes because
the box has only USB ports to connect a keyboard.

I tested run(4) device on all ports including USB 3.0 ones, but 7 times
of 10 Ralink RT3070 stops with the error when run(4) device is connected
to 6.3amd64 DURING BOOT mostly. There is no, or very rare panic when
run(4) connected and started while system booted already.

The same issue with run(4) device (it looks 'the same' from user side)
was with 6.2amd64 before. Please refer for previous posts for details.

 kernel: page fault trap, code=0
 Stopped at softclock+0x16b: movq %rax,0(%rdx)

After removing USB cable from the RT3070 no one USB device works since
than, including USB 1.1 keyboard.

Afterwards, I see this, but cant input any command to ddb because of
keyboard is not working in the moment of panic.
