I have queried the upstream linux-acpi developers mailing list about the choice to make native hwmon drivers non-functional without adding the "acpi_enforce_resources=lax" cmdline parameter. You can follow the message thread at:
http://marc.info/?t=126747745400002&r=1&w=2 It appears to be the strong belief that the functionality in 2.6.31 and later kernels are the correct solution, and even a whitelist of hardware is unwise. Thus, the default for Ubuntu will remain consistent with upstream. If you want native hwmon driver support, you will need to manually override the protection by using the aforementioned cmdline parameter. However, the boot error message does appear to be at too high of a log level. I have compiled a kernel that lowers the warning message. I need someone to test the kernel to ensure that: 1. The boot message no longer appears over the splash screen 2. The message still appears in dmesg Please find the new kernel at http://people.canonical.com/~cndougla/440470/ -- [ubuntu-boot-experience] nForce2_smbus conflicts with ACPI region SM00 https://bugs.launchpad.net/bugs/440470 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
