Checksum errors are due to the BIOS getting the checksum wrong or possibly (very very rarely) the firmware data being corrupt. It's more likely to be a BIOS bug. The original bug report reported that table TCPA was producing the error - this is not a problem since the kernel doesn't care about the checksum being correct for this ACPI table anyhow.
This is not a kernel issue, it's just a warning. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/133146 Title: ACPI Warning: Incorrect checksum in table To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/133146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
