[2.] Full description of the problem/report: The panic can be worked around by passing acpi=off on the kernel command line. Passing acpi=ht crashes. [3.] Keywords (i.e., modules, networking, kernel): - [4.] Kernel information [4.1.] Kernel version (from /proc/version): Several kernels were tested [4.2.] Kernel .config file: I used the default arch linux config (https://projects.archlinux.org/svntogit/packages.git/tree/trunk/config.x86_64?h=packages/linux), running make oldconfig and selecting the defaults. [5.] Most recent kernel version which did not have the bug: Output of git bisect: 671cc68dc61f029d44b43a681356078e02d8dab8 is the first bad commit commit 671cc68dc61f029d44b43a681356078e02d8dab8 Author: Lv Zheng Date: Wed Jan 8 13:43:34 2014 +0800 ACPICA: Back port and refine validation of the XSDT root table. Some platforms contain an XSDT that is ill-formed or otherwise invalid (such as containing some or all entries that are NULL pointers). This change adds a new function to validate the XSDT before actually using it. If the XSDT is found to be invalid, ACPICA will now fall back to using the RSDT instead. This feature is already in the Linux kernel. When it is back ported to ACPICA, code is refined to follow ACPICA coding style and this patch is the generation of the integration.
