------- Comment From [email protected] 2018-04-26 09:59 EDT------- In the KVM Scrum discussion today, it was decided that:
1) Doug will jump on boslcp3 and reboot (multiple times if needed) in an attempt to reproduce the PETITBOOT issue described in comment 191 (process_one_work crash). Once in that condition, Doug will try to blacklist the qla2xxx driver in PETITBOOT and retry to see if it makes any better. If Chanh is available, Doug could also ask him to yank out the Qlogic adapter from the box and see if the process_one_work crash can be reproduced. This is an attempt at bringing more data into the boot condition that apparently triggers after the Canonical Host Kernel hangs/crashes, but somehow persists across reboots. 2) In parallel with the above, Dwip will identify the set of upstream qla2xxx commits (and any important dependencies) that would serve as the equivalent for his tentative patch in comment 132. 3) Mauricio will use the information in [2] above to rebuild the Skiroot in Bug 167103 comment 22, but with Dwip's patch replaced by the patches in [2]. In other words, a Skiroot with the tlbie fix + whatever is pointed out in [2] 4) Similarly, Gustavo Walbon will use the information in [2] and apply it to the latest proposed Canonical Kernel (comment 186), also ensuring that the patch for Bug 166877 is applied (if not already part of the official Canonical build). 5) Once Doug is done with [1] and Mauricio is done with [3], Doug can test the skiroot in [3] to validate if it makes the PETITBOOT issue better 6) Once Doug is done with [5], Chanh can restart the long-running test, with the Skiroot provided in [3] and with the kernel provided in [4]. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762844 Title: ISST-LTE:KVM:Ubuntu1804:BostonLC:boslcp3: Host crashed & enters into xmon after moving to 4.15.0-15.16 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1762844/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
