Seen today with 5.4.19-1 (sid) on Intel HD 630 Graphics (i7 7700). 
Console nonrecoverable but system up and could be mostly shut down via

See also similar report and discussion and patch here:
https://gitlab.freedesktop.org/drm/intel/issues/827

Especially the remark "obj->frontbuffer is no longer protected by the 
struct_mutex".


Are they the upstream? I do not know if this is exactly the same bug as 
reported here, or whether they are upstream, so I have not set upstream.

Bug#949369: i915: kernel crash in i915_active_acquire()

2020-02-25 Thread Pavel Reznicek 
Source: linux
Followup-For: Bug #949369

Dear Maintainer,

  I experienced the same crash after upgrading to kernel series 5.4.x (namely 
to 5.4.8) in mid of January. The crashes of the system were quite frequent 
(every few hours, making the system unusable). After few experiments I ended up 
with the linux kernel 5.5.0-rc5 from unstable, which seems to work relativelly 
well. However, today I got the same crash already twice, despite more than 
month of using it. There are numer of reports about the problems related to the 
i915 driver in the 5.3.x-5.5.x kernel series:

Kernels 4.19.x in buster seems to be fine.

Bug#949369: i915: kernel crash in i915_active_acquire()

2020-02-18 Thread Nils Jarle Haugen 

Dear maintainers,

I experienced the same crash today. I have the Lenovo t470p with the 
i915 (Intel HD 630 graphics) and the NVIDIA 940MX dedicated graphics 
card. I statically switch between intel and nvidia with xrandr and sddm 
scrpts (using 
https://wiki.debian.org/NvidiaGraphicsDrivers/Optimus#Configuration).


On the occasion when the system crashed, the xrandr and sddm scripts 
were commented out and not actively in use (but the nvidia kernel module 
was still loaded).


The crash left the system in a unusable state, needed to call sysrq to 
force restart it.


I'll try to purge the proprietary drivers and then try to reproduce the 
issue.



Kind regards,
Nils J. Haugen

I was unable to reproduce the issue even without doing any modification to
the system.

Feel free to close the bug. I can reopen it in case I have followups.

Is this reproducible without the Nvidia proprietary driver?
