VMAP_STACK is new on riscv since v5.14 kernel, meaning we haven't shipped any releases on riscv with VMAP_STACK enabled.
At the time when VMAP_STACK was enabled in the kernel nobody had EFI for riscv yet either. So it makes sense that this issue is being experienced by us just now, once we got all the pieces landing together. I would be in favour to disable VMAP_STACK, on riscv64 only, until we have more fixes to make it work better. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967130 Title: rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-riscv/+bug/1967130/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
