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 commit e93b2da9799e5cb97760969f3e1f02a5bdac29fe Author: Christian König <christian.koenig@xxxxxxx> Date: Sat Oct 24 13:11:29 2020 +0200 drm/amdgpu: switch to new allocator v2 It should be able to handle all cases here. v2: fix debugfs as well Signed-off-by: Christian König <christian.koenig@xxxxxxx> Reviewed-by: Dave Airlie <airlied@xxxxxxxxxx> Reviewed-by: Madhav Chauhan <madhav.chauhan@xxxxxxx> Tested-by: Huang Rui <ray.huang@xxxxxxx> Link: https://patchwork.freedesktop.org/patch/397086/?series=83051&rev=1 drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 45 ++++++++++----------------------- 1 file changed, 14 insertions(+), 31 deletions(-) Detailed bisect log is here: https://bin.privacytools.io/?a88ae63fb95fa1c1#EtrC4qxGWjmgy5C3dBzXFGqjxc7znTKULtz4cxoYFxW5 Best regards, Luís Mendes Aparapi developer PhD Student & Researcher _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
