Public bug reported: Under Ubuntu 18.04 LTS with HWE-Kernel 5.4.0-52-generic the command
btrfs subvolume list / sometimes leads to a segmentation fault. Unfortunately I cannot figure out why some calls of this command work as expected while others (of exactly the same command) lead to the segmentation fault. On my machine about every third call leads to the segfault. In case of the segmentation fault, my syslog contains the following entries: Nov 2 13:56:11 Sputnik kernel: [153948.460139] btrfs[19583]: segfault at 7ffcd9d8c391 ip 000055d8e5201117 sp 00007ffcd5d8bd20 error 4 in btrfs[55d8e5195000+a9000] Nov 2 13:56:11 Sputnik kernel: [153948.460153] Code: 00 00 31 c0 8b 5c 24 14 39 9c 24 88 00 00 00 0f 86 f2 01 00 00 48 8b 7c 24 08 48 8d 57 68 48 8d 0c 02 48 83 c0 20 48 89 04 24 <8b> 71 18 8b 79 1c 48 8b 59 08 48 8b 69 10 81 fe 90 00 00 00 89 74 According to https://forums.linuxmint.com/viewtopic.php?t=333594 I do not seem to be the only one experiencing this problem. ** Affects: btrfs-progs (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902525 Title: btrfs subvolume list segmentation fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/btrfs-progs/+bug/1902525/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
