Thank you,

Yes, resume. 

Comment 0 mentioned: 

* the panic occurring when the OS woke from sleep

* the silence (no debug beep). 

There would have been a simple press of the power button either on the computer
(HP ZBook 17 G2) or its HP dock (to which three L2ARC devices were connected,
if that's relevant). I most often use the button on the computer, not on the
dock.

From the time of the dump (09:45), I'm fairly certain that the wake was at
work, after sleeping the OS at home. 

Bug 283015 comment 1 has the result of a probe for the same computer. 

8086:08b1:8086:c060 is at
<https://bsd-hardware.info/?probe=c8d95da1f8#pci:8086-08b1-8086-c060>.

HTH

For now, I reverted to iwm(4), mostly because I must avoid disruptions such as
kernel panics during working hours. 

Less selfishly, iwlwifi(4) _is_ amongst my priorities for the community, so if
you think that there'll be benefit from me reproducing the issue, I might aim
to do so by travelling elsewhere.
