Lv Zheng from Intel reported on the Kernel Bug Tracker that a fix may be available. I've tested using the 3.12-rc2 kernel from the Ubuntu mainline PPA with good results, but additional testing is needed before I can report back that it fixes the problem. See his comment reproduced below:
<quote> Have you tested the kernel with an ACPICA fix that has filled a gap for operation region fields? The commit is: Commit 4be4be8fee2ee99a52f94f90d03d2f287ee1db86 Author: Bob Moore <robert.mo...@intel.com> 2013-09-06 06:27:15 (GMT) Subject: ACPICA: Fix for a Store->ArgX when ArgX contains a reference to a field. Which is shipped in the mainline kernel tagged as 3.12-rc2. This bug seems to be a duplicate of the issue fixed by this commit. </quote> If you can, please either install the 3.12-rc2 kernel from the Ubuntu Mainline Kernel PPA or download and compile from source a 3.12-rc2 kernel and test on a system as unmodified as possible (no DSDT modifications, init script hacks, or otherwise) and report back. The mainline kernel PPA's debs for 3.12-rc2 are tagged as Saucy (13.10), but should install and boot on any Ubuntu version back to 12.04 (maybe even earlier).
