SubjectGeneral protection fault: RIP: 0010:free_block+0xdc/0x1f0
Date
Dear Andrew folks, dear Linux folks,


With Linux 5.9-rc4 on a Dell OptiPlex 5080 with Intel Core i7-10700 CPU
@ 2.90GHz, and external

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices,
Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM] [1002:6611] (rev 87)

running graphical demanding applications glmark2 [1] and the Phoronix
Test Suite [2] benchmark *pts/desktop-graphics* [3]

$ git describe --tags
v10.0.0m1-13-g0b5ddc3c0

I got three general protection faults, and it restarted or froze (no
input devices working, screen froze and even network card (no ping)).

Here the system restarted itself:

Here it froze:
