This is a regression caused by CONFIG_VMAP_STACK. The driver uses __pa (phys_to_virt) on a stack address which does not work with virtual mapped stacks.
To solve this upstream will require a bit more work, I'm attaching a minimal patch to work-around by using kmalloc for the problematic allocation. ** Patch added: "zip.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1755073/+attachment/5090802/+files/zip.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755073 Title: ubuntu_zram_smoke test will cause soft lockup on Artful ThunderX ARM64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1755073/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
