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
https://pastebin.com/pcuUWXbj
I've bisected and traced the problem to this commit:
e93b2da9799e5cb97760969f3e1f02a5bdac29fe is the first bad commit

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

Hi Luis,
adding Daniel as well.
first of all can you please create a bug report for this here:
https://gitlab.freedesktop.org/drm/amd/-/issues This way we can better
track issues.
Then what seems to happen is that somebody is using the TTM pages in a
way they are not supposed to be used.
We have found a bunch of bugs in for example KVM since adding that
commit and I have the strong suspicion that is just another one of those.
Regards,
Christian.
