I've seen those on every machine so far when ran long enough. Since I believe we've clearly demonstrated that this is an unrelated failure, I've split it out into bug 1860013 - let's track it there. > There was also another issue during one of the reboots which is probably > unrelated and due to a flaky BMC: Let's track that in bug 1857073. Even if it is a flaky BMC, the IPMI driver should handle the failure gracefully. Did you see this on host 'wright' as well? -dann -- 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/1857074 Title: Cavium ThunderX CN88XX Panic : Unknown reason Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Bug description: Series: Bionic Kernel: 4.15.0-74.84 linux-generic Steps to reproduce: Install 4.15.0-74.84 Kernel and boot the system. The following crash was observed while testing the proposed kernel for the 2019.12.02 SRU Cycle. This kernel was built to include fixes for the following bugs: * [Regression] Bionic kernel 4.15.0-71.80 can not boot on ThunderX (LP: #1853326) - Revert "arm64: Use firmware to detect CPUs that are not affected by Spectre-v2" - Revert "arm64: Get rid of __smccc_workaround_1_hvc_*" * [Regression] Bionic kernel 4.15.0-71.80 can not boot on ThunderX2 and Kunpeng920 (LP: #1852723) - SAUCE: arm64: capabilities: Move setup_boot_cpu_capabilities() call to correct place The following crash appears to be a NEW bug. not related to the prior bugs listed above. This bug DOES NOT APPEAR to be related to LP#1857073. This is another NEW BUG. Hostname: Starmie Probable Cause is unknown at this point and still under investigation.
