Well now,
I just plugged the UPS into the USB2 port after unplugging the hub...
and the thing panics again!
So it was probably not the USB1 Hub on the KVM.
I'll get you the dump from earlier and the new one later tonight, will
grab dinner now.
I can do some more testing but probably not until the weekend.
Regards
Jorge

USB3 Key: works fine if plugged in USB3 port!
I moved to back to the USB2 port and I plugged in the 2 devices that
were in the hub into the 2 USB3 ports but the box creating a dump now
:s
Do you want me to send you the dump?
Yes, please that'd be very useful.
Also the output from the kernel there is also quite useful. The being
unable to get the devices to transition is quite useful in
understanding
what happened, though there are some confusing messages. I'm a bit
surprised that we saw the slot disabling fail -- another thing to look
into.
Thanks,
Robert

I noticed on the console that it complains about not being able to
bring online some of the USB stuff.
I also included the dmesg snippet from the time.
It did seem to detect the USB key so I will see if I can get that to
work and leave the kb in the hub connecto to usb2

I just upgrade one of my compute nodes.
No crashes yet, but nothing plugged into the USB3 ports is
working.
I tried a USB-keyboard and a USB3 Drive.

Hmm, one of the Renesas controllers, not one we've seen yet. Also
one of
the ones more often reported to be troublesome.
If you have the time, can you please plug things back into USB 3
ports,
reboot, and then run the following:
/usr/lib/xhci/xhci_portsc -v
Along with the mdb -ke '::prtusb'. Could you also check if there's
anything got logged about that?
I added everything to a gist for easier reading:
https://gist.github.com/sjorge/47cb7f5e14b335c3c3c382dd3daf4e4f
This is with the boot USB plugged into the first USB3 port (it
always
works at boot, even before the xhci work)
The small USB2 hub with my keyboard (KVM) and UPS plugged in
attached to
the second USB3 port.
Thanks for the additional information. It looks like one of your
ports
is stuck trying to transition in the device state machine.
Unfortunately
it's a bit hard to get a mapping between the virtual ports on the
controller and the physical ports on the machine.
I'm not entirely sure why it would be stuck in that state, from the
spec
it makes it sound like it's supposed to transition that way on its
own
without any intervention from the host.
It does look like we detected one of the devices, but for some
reason
that fact didn't make it to the kernel per se. Would it be possible
for
you to run cfgadm -al in both cases?
Sorry I don't have a more immediate answer for what's happening
here.
I'm not sure yet what's different about your setup from others --
though
more likely than not there's some driver bug at the root of it all.
