If the computer is hanging as you describe, this is a kernel bug, possibly exacerbated by a hardware bug. It isn't a userspace bug; e2fsprogs is just reading from the block device. If that is causing the computer hang, it's by definition not a userspace bug.
So this needs to be a kernel investigation; can it be reliably reproduced? What kernel version is it? What is the hardware --- especially what kind of storage device, and how is it connected to the computer? If you hook up a serial console, are there any interesting kernel messages, including potentially device driver messages indicating some kind of hardware issue (e.g., media errors, etc.) In any case, this needs to be redirected to the kernel, and if you have an LTS support contract, I'd suggest contacting Canonical's enterprise support to work the kernel issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/1897741 Title: hang after using util badblocks Status in e2fsprogs package in Ubuntu: New Bug description: sudo badblocks -v /dev/sdb2 > badsectors.txt after this command my computer hang, keyboard/mouse not working, no reaction, no ping in local network only hardreset can help sudo fdisk -l | grep /dev/sdb2 /dev/sdb2 206848 1422700543 1422493696 678,3G 7 HPFS/NTFS/exFAT ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: e2fsprogs 1.44.1-1ubuntu1.3 ProcVersionSignature: Ubuntu 5.4.0-48.52~18.04.1-generic 5.4.60 Uname: Linux 5.4.0-48-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.17 Architecture: amd64 CurrentDesktop: XFCE Date: Tue Sep 29 16:00:24 2020 InstallationDate: Installed on 2020-03-09 (204 days ago) InstallationMedia: Xubuntu 18.04.4 LTS "Bionic Beaver" - Release amd64 (20200203.1) SourcePackage: e2fsprogs UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1897741/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
