Hi Viktor, Confirmed - I've switched srv04 back to plain v6.8.12, boot params removed (`processor.max_cstate=1 idle=nomwait` no longer in GRUB_CMDLINE_LINUX_DEFAULT). Verified via `/proc/cmdline` that they're gone.
Fresh boot, all 14 guest VMs running. I'll watch this closely over the next few days for the baseline reproduction. srv05 and srv07 remain untouched as you suggested. -- 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
