Created attachment 820773 [details] /sys/firmware/acpi/tables/FPDT taken from system Description of problem: I've upgraded to systemd-208-4 (together with Fedora 20) on my Acer Aspire One D270 netbook and suffered stuck during boot after systemd launched (in initramfs). I've tried acpi=off and system booted. After code investigation I found that acpi_get_boot_usec in src/shared/acpi-fpdt.c is stuck in loop if rec->length is zero. Version-Release number of selected component (if applicable): systemd-208-4 How reproducible: always Steps to Reproduce: 1. read FPDT in attachment using acpi_get_boot_usec function Actual results: function is stuck in loop Expected results: function returns -EINVAL or something else, but doesn't loop Additional info: I have current BIOS for system.
