            Bug ID: 206987
           Summary: [drm] [amdgpu] Whole system crashes when the driver is
                    in mode_support_and_system_configuration
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.5.11
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: evvke@hotmail.com
        Regression: No

Whole system crashes with this error message : simd exception: 0000 [#1]
PREEMPT SMP NOPTI

Only giving a REISUB treatment works.

And cause is amdgpu driver.

Please attach your full dmesg output.  What version of gcc are you using?

dmesg output 2

This crash happened again. In that time I have used VLC, played a game (GZDoom)
and tried to listen youtube playlist by using a combination of youtube-dl,
ffmpeg and mpv.

I also updated motherboards BIOS/firmware to latest one.

And another one. It seems that switching between virtual consoles causes this
bug to happen

I am having the same problem sometimes during start/exit of SteamVR.
I have observed with the 5.6 kernels.
My card is a Navi RX 5700XT.

And it happened again. Looks like that something goes wrong after while when
computer monitor is turned on.

dmesg output from Linux 5.7-rc3

This is starting to be real problem, I can't do anything remotely productive.
Crash will happen in just 12 hours (give or take) when system is rebooted from
previous one.

I'm running four LXC containers which I have setup to run GUI programs in hosts
system by following this help :
https://wiki.archlinux.org/index.php/Linux_Containers#Xorg_program_considerations_(optional)

Also I have running VirtualBox but its VM's aren't accessing 3D functions from
host at all.

dmesg from 5.6.8

Additionally dmesg output shows this line : note: kworker/0:3[2251663] exited
with preempt_count 1

It seems that this bug occurs when the monitor is turned off and then on
repeatedly with short delay between.

--- Comment #16 from Petteri Aimonen (jpa@kernelbug.mail.kapsi.fi) ---
I hit the same issue, using Ubuntu 20.04. It happened when switching window to
Firefox. For me it only crashed Xorg, ssh to the machine still worked ok.
Killing Xorg didn't work and `shutdown -r now` hung up somewhere.

Here is a bug report on the Ubuntu package:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881134

Here is call trace decoded with the debug symbols:

--- Comment #18 from Petteri Aimonen (jpa@kernelbug.mail.kapsi.fi) ---
As best as I can tell, the crash seems to be caused by some floating point
exception (such as underflow/overflow) in this function call in dcn_calc_auto.c
line 176:

dcn_bw_ceil2(v->byte_per_pixel_in_dety[k], 1.0)

In dcn_bw_ceil2() the exception occurs in this instruction:

addsd  0x0(%rip),%xmm3

which is performing the addition flr + 0.00001.
At this point %xmm3 is ((int)(v->byte_per_pixel_in_dety[k] / 1.0)) * 1.0
The variable byte_per_pixel_in_dety is only assigned constant values 1.0, 2.0,
4.0, 8.0 so
I don't see any reason for addsd to cause a simd exception. I'm not sure if the
exception
is precise or if it could be delayed from some prior instruction, but AFAIK it
should be
precise because in usermode the exception handler would attempt a recovery.

Having XMM3 or MXCSR values would help, but they don't seem to get included in
the dmesg output and I'm not sure if they are available in a crash dump either.

Google search turned up
https://beowulf.beowulf.narkive.com/tAHxVcs0/simd-exception-kernel-panic-on-skylake-ep-triggered-by-openfoam
where the exception was delayed for some reason.

Analyzing the dmesgs attached to this bug report, we have following crash
locations:

Cyrax    2020-03-26 21:36: divss  xmm0,DWORD PTR [r14+0x17f8]
Cyrax    2020-04-04 07:40: divss  xmm0,DWORD PTR [r14+0x17f8]
Cyrax    2020-04-18 13:19: divss  xmm0,DWORD PTR [r14+0x17f8]
farmboy0 2020-04-19 11:43: not a simd exception
Cyrax    2020-04-23 05:15: divss  xmm0,DWORD PTR [r14+0x17f8]
Cyrax    2020-04-27 19:20: divss  xmm0,DWORD PTR [r14+0x17f8]
Cyrax    2020-05-02 14:18: divss  xmm0,DWORD PTR [r14+0x17f8]
PetteriA 2020-05-28 16:05: addsd  xmm3,QWORD PTR [rip+0x1de967]

So the crash locations appear fairly consistent for Cyrax's machine, but no two
machines have the same location.

For other users affected by this problem, it could be helpful if you install
kernel debugging symbols and use decode_stacktrace.sh to convert the raw stack
trace to code locations.
