commit: f6668a70defec83ec0c837e052dd5490b66068d3 [1133/1153] drm/amdgpu: add timeout flush mechanism to update wptr for self interrupt
config: alpha-allmodconfig (attached as .config)
compiler: alpha-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout f6668a70defec83ec0c837e052dd5490b66068d3
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=alpha
If you fix the issue, kindly add following tag as appropriate
