I have experienced same issue with all karmic kernels acpi laxing is not a real fix even if it suppresses the error, in some way the must be some IO probing being done by acpi and sensors banging IO ports which I understand can be harmful for hw. The asrock ION family has a hw monitoring/control chip with no drivers available in the wild from either Asrock or Linux communities. Asrock first line support say W83677HG-I (the chip in question) has linux drivers yet nowhere are they to be found.
I believe that this chip is also part of solving this issue properly lm- sensors project have a request for such driver but nothing so far is up. Also noticed issues with kernels up to -18 karmic flavours have issues with supporting modules like coretemp for instance where the coretemp.ko must be compiled in order to work. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/485234 This is all related IMO. -- [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
