commit: 6e260fc2770c157f81704b403e6e3d40e0e10f97 [10089/10108] clocksource/drivers/timer-ti-dm: ack pending interrupt during suspend
config: arm-defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (GCC) 11.2.0
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 remote add ti git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
git fetch --no-tags ti ti-rt-linux-5.10.y
git checkout 6e260fc2770c157f81704b403e6e3d40e0e10f97
# save the attached .config to linux build tree
