I spent some time testing kdump. I had to disable IOMMU to get kexec/kdump to work. Not sure why because neither the smartpqi driver nor our controllers care about IOMMU settings. So, this perhaps is a platform issue. I used the following kdump settings: /etc/default/grub.d/kdump-tools.cfg GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=512M-:640M" vi /etc/default/kdump-tools KDUMP_KEXEC_ARGS="--elf64-core-headers" #KDUMP_CMDLINE="" KDUMP_CMDLINE_APPEND="reset_devices systemd.unit=kdump-tools-dump.service nr_cpus=1 irqpoll nousb ata_piix.prefer_ms_hyperv=0 acpi_no_memhotplug numa=off lapic pci=nommconf pci=biosirq nosmep mem_encrypt=off" Not sure what all is really required, but kdump works with all of the above settings. ls -ltr /var/crash/202108271939/ total 2374244 -r-------- 1 root root 33816203264 Aug 27 19:40 vmcore.202108271939 root@sys2m2935031x:~# date Fri 27 Aug 2021 07:45:45 PM UTC All of my other tests looked good. fio performance testing - No regressions. reboot testing configuration testing - (using our SSA tools to switch between RAID and HBA mode) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933518 Title: Update SmartPQI driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1933518/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
