Greetings everyone.
I ran the cat on the proc files for the reference pid before I sent the first
email, however here it is, since I never listed the contents.
sudo cat /proc/91/stack
[<ffffffffffffffff>] 0xffffffffffffffff
And when following the information from the closed bugzilla debug info, I get
the following:
cat /sys/kernel/debug/tracing/trace_pipe |grep cpu=7
kworker/7:1-91 [007] d.s. 211349.026006: workqueue_queue_work: work
struct=ffff88083edcfff0 function=cs_dbs_timer workqueue=ffff88081e008c00
req_cpu=7 cpu=7
kworker/7:1-91 [007] d... 211349.123123: workqueue_queue_work: work
struct=ffff88080e2ba2f8 function=nouveau_connector_hotplug_work [nouveau]
workqueue=ffff88081e008c00 req_cpu=5120 cpu=7
kworker/7:1-91 [007] d.h. 211349.123156: workqueue_queue_work: work
struct=ffff88080e30e448 function=nvkm_connector_hpd_work [nouveau]
workqueue=ffff88081e008c00 req_cpu=5120 cpu=7
These messages are cyclically printed to the trace_pipe file, in this order.
I figured that this may be sourced within the fact that the nouveau driver is
being used, instead of the NVidia drivers I was using last fall while doing
CUDA research.
I had a Titan in there, and have reverted back to a more basic card, just prior
to the water cooler dying.
I re-installed the newest NVidia driver from nvidia and the kworker issue
disappears.
However, true to Linux form, this action has somehow screwed up my GUI
experience, causing 1) the graphic window manager fails to start, and just sits
there in the text based startup screan saying it is trying to start GNOME Login
Manager, etc.. 2) If I remove GNOME and reinstall KDE you boot into a text
based login, and once in there you can startx and KDE will start, but as soon
as I try to open firefox the GUI dies, and the messages say something about a
ksmserver not being accessible, etc...
However, with KDE running, I have full access to the NVidia management tools,
so it was working, with HDMI audio on the second monitor, etc...
So now I have to fix my GUI desktop environment, for whatever reason, however,
all basic services are running such as the VMs and DNS, etc...
Respectfully,
Martes G Wigglesworth
