Ubuntu 15.04: Multiple ACPI errors on Asus notebook

[aljosa]

LiveUSB environment (daily-live 23-Mar-2015)
Asus optimus notebook X750JN-TY027H (Intel® Core™ i7-4710HQ; RAM 8GB; Nvidia GeForce GT 840M)

Hello,
I have received an expert's opinion that most probably they have nothing to do with the Elantech touchpad bug (https://bugzilla.kernel.org/show_bug.cgi?id=94981), so in order to contribute to quality improvement of the new Ubuntu 15.04, I'm reporting a problem I found in this "beta" version - related to mutliple ACPI warnings and errors. Here's an example:

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Problem is present also in Ubuntu 14.04.2 and here you can find dmesg output with kernel 4.0-rc4:
