Was using my machine normally, then my mouse cursor vanished. After switching
to a VT and back to X11, my cursor came back. But I did notice a nasty trace in
dmesg (below).
I have a few options specified on my command line related to i915, but these
worked fine through 3.13.9:
i915.lvds_downclock=1 i915.i915_enable_rc6=7 i915.i915_enable_fbc=1
System is a Lenovo ThinkPad S1 Yoga.

Let me know what other information would be helpful. I could do a bisection if
needed, but I'm hoping the stack traces below trigger an "aha" moment in somebody.
Here's the trace:

Was using my machine normally, then my mouse cursor vanished. After switching
to a VT and back to X11, my cursor came back. But I did notice a nasty trace in
dmesg (below).
I have a few options specified on my command line related to i915, but these
worked fine through 3.13.9:
i915.lvds_downclock=1 i915.i915_enable_rc6=7 i915.i915_enable_fbc=1
System is a Lenovo ThinkPad S1 Yoga.

Let me know what other information would be helpful. I could do a bisection if
needed, but I'm hoping the stack traces below trigger an "aha" moment in somebody.
Here's the trace:

I don't think the trace below is related to the cursor disappearing.
I found a pair of bugs (one in the intel driver, one in the X server)
which can cause cursor disappearances. I just sent an intel driver patch
to the intel-gfx list with the subject:
[PATCH] load_cursor_argb is supposed to return a Bool, not void
I've posted the X server patch once, and will respond to some review
comments. Either is sufficient to get a cursor back, the intel driver
one means you get a working hardware cursor again, rather than using a
software cursor by mistake.

Any idea what the trace is all about then? Seems it has something to do
with runtime power management (maybe my aggressive kernel command-line
options are triggering it).

As Julien points out, this bug only affects people running master from

Please test without them. Currently runtime pm should be disabled still on
vlv (since it's incomplete in 3.14). If you've force-enabled that then you
get to keep all pieces ;-)
In general don't set any i915 options if you're not a developer or someone
else who _really_ knows what's going on.

Note that the lspci output and the
[ 1795.275026] [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed
register before writing to 70084
line suggests HSW and the specs for ThinkPad Yoga suggests the same. But
I don't know how the vlv_* functions can possible end up in those traces
then, perhaps just a coincidence, random data on stack?
For HSW the rc6 kernel option shouldn't make a difference.

I'm wondering the same. Perhaps double check your kernel build and
modules are all right and matching?

It was a clean build (built in a clean chroot, no ccache or anything
fancy), so those stack traces are as "right" as they could be under
those conditions.
The "good" news (or perhaps scary news) is that I've been running
3.14.1 for the past 36 hours and haven't been able to reproduce either
problem since then (warnings or ninja mouse cursor). Nothing in the
changelog for v3.14..v3.14.1 really stands out as a clear fix though.
The only changes that appear to directly affect my configuration would
be the futex changes, iwlwifi change, efi change, and ipv6 change.

This issue is haunting me again. This time I'm running 3.14.6. My mouse
cursor vanished, and I have a bunch of warnings in dmesg:

As before, the stack trace doesn't make sense to me above this line on
a HSW machine, all I can think of is a problem in your build (you ruled
it out), or a problem in the kernel's stack unwinding. In any case the
below drm_mode_cursor_ioctl line and the unclaimed register write
messages match and it seems that the problem happened already earlier
since the unclaimed flag was already set when we got here.
I think the best way forward would be to open a bug at bugs.freedesktop.org
and provide a dmesg log when the problem happens with drm.debug=14
kernel parameter set.
