The warning messages occurred between "ACPI: EC: interrupt blocked" and "ACPI: EC: interrupt unblocked". Let's try to apply all (17) mainline patches to ACPI EC to Ubuntu-5.4.0-47.51.
If this solves the problems we can then bi-select to identify which patches are the solution and then backport to 5.4 kernel. The test kernel is available @ https://people.canonical.com/~alexhung/LP1896482/ and the applied patches are listed in ec_patches.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896482 Title: acpi event detection crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896482/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
