[bugreport] [5.10-rc1] Oops: 0000 [#1] SMP NOPTI bug which always starts as page allocation failure

From: Mikhail Gavrilov
Date: Tue Nov 03 2020 - 16:22:31 EST

Hi folks.
I observed hard reproductible the set of bugs.
It always started as
1) kworker/u64:2: page allocation failure: order:5,
mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO),
nodemask=(null),cpuset=/,mems_allowed=0
Continious as:
2) WARNING: CPU: 21 PID: 806649 at
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:7505
amdgpu_dm_atomic_commit_tail+0x23bd/0x24e0 [amdgpu]
And ended as:
3) BUG: unable to handle page fault for address: 0000000000012488
Which annoing because lead to completely computer hang.

Example of one log:

[11561.927250] kworker/u64:10: page allocation failure: order:5,
