Hi Radovan, Yes, switching srv04 back to plain 6.8.12 without the boot params makes complete sense.
If it panics again within a few days, that confirms the baseline repro on this hardware and proves the idle/C-state params were what kept it alive for 19 days by altering the wake-up latency. If it stays up, then we know the original 3-day crash was an outlier. Leaving srv05 (both commits) and srv07 (commit 1) running as-is while srv04 runs the baseline test sounds like the best path forward. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163642 Title: Kernel panic "Attempted to kill the idle task" on AMD Opteron multi- node NUMA under KVM (6.8.0-137) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163642/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
