Subject: Regression: bisected: AMDGPU causes Kernel Bad page state OOPS starting with kernels 5.11.x, 5.12.x, 5.13-rc
Date: Mon, 24 May 2021 20:25:31 +0100 [thread overview]
Message-ID: <CAEzXK1pXrnXpBfzZ9c-8MsYpoDCRt86F7yU=uLi52i96u8+SQA@mail.gmail.com> (raw)
Hi,
AMDGPU was working fine on my armhf systems with 5.10.x and previous
kernels and a RX550 card. Unfortunately I have only now tested kernels
5.11.x, 5.12.x and 5.13-rc and all are now showing problems like this
one:
May 10 20:23:14 picolo kernel: [ 18.967626] BUG: Bad page state in
process gnome-shell pfn:78c08
May 10 20:23:14 picolo kernel: [ 18.973750] page:ce2e9717 refcount:2
mapcount:1 mapping:17edced0 index:0x109e9 pfn:0x78c08
May 10 20:23:14 picolo kernel: [ 18.973763] aops:0xc0e12f54 ino:30d
Full Kernel boot log is here

I've bisected and traced the problem to this commit:
e93b2da9799e5cb97760969f3e1f02a5bdac29fe is the first bad commit
commit e93b2da9799e5cb97760969f3e1f02a5bdac29fe

drm/amdgpu: switch to new allocator v2
It should be able to handle all cases here.
