------- Comment From cborn...@de.ibm.com 2020-03-13 03:59 EDT------- Can you collect lsdasd -l lsdasd -v
also the complete result of dbginfo.sh (as this contains the debuglog for the dasd driver) If you can easily reproduce the issue it might be helpful to increase the log level, but lets start with the defaults. Can you also check if there is something in the z/VM logs? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1867118 Title: dasd_fba io error and kernel panic Status in Ubuntu on IBM z Systems: Incomplete Status in linux package in Ubuntu: Incomplete Bug description: Generated I/O errors every hour in syslog and caused kernel panic with workloads running ---uname output--- Linux ubuntutest01 4.15.0-88-generic #88-Ubuntu SMP Tue Feb 11 20:11:02 UTC 2020 s390x s390x s390x GNU/Linux ---Patches Installed--- distro provided. up-to-date from Ubuntu18.04.
