Description of problem: After upgrading a system to CentOS Stream 9, I found that blkid hangs indefinitely and cannot be killed with kill -9. Version-Release number of selected component (if applicable): util-linux-core-2.37.4-11.el9.x86_64 How reproducible: Always Steps to Reproduce: 1. blkid 2. 3. Actual results: The command hangs and cannot be killed. Expected results: print results and exit. Additional info: When I run "strace blkid", it gets this far before hanging: openat(AT_FDCWD, "/dev/block", O_RDONLY|O_NONBLOCK|O_CLOEXEC|O_DIRECTORY) = 6 newfstatat(6, "", {st_mode=S_IFDIR|0755, st_size=580, ...}, AT_EMPTY_PATH) = 0 getdents64(6, 0x5581f1f973f0 /* 29 entries */, 32768) = 792 newfstatat(6, "251:0", {st_mode=S_IFBLK|0660, st_rdev=makedev(0xfb, 0), ...}, 0) = 0 close(6) = 0 readlink("/dev", 0x7ffd64ed6bd0, 1023) = -1 EINVAL (Invalid argument) readlink("/dev/block", 0x7ffd64ed6bd0, 1023) = -1 EINVAL (Invalid argument) readlink("/dev/block/251:0", "../pktcdvd/pktcdvd0", 1023) = 19 readlink("/dev/pktcdvd", 0x7ffd64ed6bd0, 1023) = -1 EINVAL (Invalid argument) readlink("/dev/pktcdvd/pktcdvd0", 0x7ffd64ed6bd0, 1023) = -1 EINVAL (Invalid argument) access("/dev/block/251:0", F_OK) = 0 newfstatat(AT_FDCWD, "/dev/pktcdvd/pktcdvd0", {st_mode=S_IFBLK|0660, st_rdev=makedev(0xfb, 0), ...}, 0) = 0 openat(AT_FDCWD, "/sys/dev/block/251:0", O_RDONLY|O_CLOEXEC) = 6 openat(6, "dm/uuid", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) close(6) = 0 openat(AT_FDCWD, "/dev/pktcdvd/pktcdvd0", O_RDONLY|O_NONBLOCK|O_CLOEXEC And ltrace shows this: setlocale(LC_ALL, "") = "LC_CTYPE=en_US.UTF-8;LC_NUMERIC="... bindtextdomain("util-linux", "/usr/share/locale") = "/usr/share/locale" textdomain("util-linux") = "util-linux" __cxa_atexit(0x55e5f93735b0, 0, 0x55e5f937a760, 0) = 0 getopt_long(1, 0x7ffd9b5c8458, "c:DdgH:hilL:n:ko:O:ps:S:t:u:U:w:"..., 0x55e5f937a780, nil) = -1 blkid_get_cache(0x7ffd9b5c7e30, 0, 0x7fcb7ba02300, 0) = 0 blkid_probe_all(0x55e5fb363520, 0x55e5fb363770, 0, 0x7fcb7b93e8bb I note that this system has a USB cd/dvd drive attached: [root@ti11 ~]# lsusb | grep -i dvd Bus 001 Device 005: ID 093b:002c Plextor Corp.
