for line in dmesg:    
    #print line.strip()
     for ident, regex in kernel_problems.items():
            if regex.match(line):
                #sys.stderr.write("%s : %s\n" % (ident, line.strip()))
                matched.append("%s" % (ident))



#python2和3的兼容输出
from distutils.log import warn as printf
printf(len(matched))
#输出结果为dmesg中包含错误信息的行数
#原理比较简单，就是获取dmesg的输出，然后逐行比对是否存在报错信息
