--- Comment From y...@cn.ibm.com 2020-03-12 22:51 EDT--- We are running it on z15. We have other distros running on this env with FBA. We don't see that issue. Here is an additional info I just found out. If I switch the kernel back to 4.4.0-174-generic, I don't see those errors anymore.

--- 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867118 Title: dasd_fba io error and kernel panic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1867118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
