Comment 20 for bug 897773

To fix the problem for checkbox, we may add "vpd" to the excluded list in below statement.

line 443 in udev_resource:
        for name in names:
            name_path = posixpath.join(sys_path, name)
            if name[0] == "." \
               or name in ["dev", "uevent", "vpd"] \
               or posixpath.isdir(name_path) \
               or posixpath.islink(name_path):
                continue
The udev_resource with excluded "vpd" will not cause the halting problem.
