------- Comment From [email protected] 2024-10-22 14:01 EDT------- Note that kfence fix brings down the memory requirement for fadump capture kernel but does not guarantee a success dump capture. So, fadump capture kernel hitting OOM in this case does not have to be considered a test fail. Also, note that the initial failure reported fails much earlier in the capture kernel boot unlike the kernel with the kfence fix patch, where it made forward progress and triggered an OOM killer eventually due to insufficient memory.
The memory requirement for fadump capture kernel is a moving target that depends on resources and services on the system. In summary, the kfence patch is still needed. Kowshik, please try increasing the memory reserved for fadump from 512M to 768M or 1024M and see if that results in a successful dump capture.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060039 Title: [Ubuntu-24.04] FADump with recommended crash size is making the L1 hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2060039/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
