Hi Huacai,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master

commit: 366bb35a8e48198cefcd3484ac6b2374d1347873 LoongArch: Add suspend (ACPI S3) support
date: 1 year, 4 months ago
config: loongarch-randconfig-r034-20230511 (https://download.01.org/0day-ci/archive/20240331/202403311326.Dr2HlMYm-lkp@xxxxxxxxx/config)
compiler: loongarch64-linux-gcc (GCC) 12.3.0
reproduce: (https://download.01.org/0day-ci/archive/20240331/202403311326.Dr2HlMYm-lkp@xxxxxxxxx/reproduce)
