Warn message reffers to the shmem_free_blocks():

     static void shmem_free_blocks(struct inode *inode, long pages)
     {
	struct shmem_sb_info *sbinfo = SHMEM_SB(inode->i_sb);
	if (sbinfo->max_blocks) {
		spin_lock(&sbinfo->stat_lock);
               ^^^^
              Here is a place where cpu1 is in a loop .

It seems like someone already held &sbinfo->stat_lock.

Can you do "sysrq-p" , "sysrq-t", "sysrq-w"  in the host ?
