Successfully verified on xenial using proposed package - adjusted the tags accordingly.
Added a section regarding regression risk to the bug description. ** Attachment added: "verification_xenial.txt" https://bugs.launchpad.net/ubuntu/+source/s390-tools/+bug/1799208/+attachment/5236277/+files/verification_xenial.txt ** Description changed: dbginfo.sh does not complete on Ubuntu 16.04(.5) using s390-tools version 1.34.0-0ubuntu8.7 Execution starts and proceeds until step 4 'sysfs': $ sudo dbginfo.sh dbginfo.sh: Debug information script version 1.34.0-build-20180502 Copyright IBM Corp. 2002, 2016 Hardware platform = s390x Kernel version = 4.15.0 (4.15.0-33-generic) Runtime environment = LPAR 1 of 10: Collecting command output - + 2 of 10: Collecting z/VM command output skipped - no z/VM environment - + 3 of 10: Collecting procfs - + 4 of 10: Collecting sysfs 'dd' process with 100% CPU can be seen: - # ps aux | grep [d]d\ + # ps aux | grep [d]d\ root 257158 100 0.0 2120 664 pts/0 R+ 06:51 11:18 dd if=/sys/kernel/debug/tracing/trace status=noxfer iflag=nonblock of=/tmp/DBGINFO-2018-10-22-06-49-52-s1lp15-1F8F67//sys/kernel/debug/tracing/trace Happens on 16.04.5 with kernel 4.4 or HWE kernel 4.15.
