Bug still present on Ubuntu 16.04 LTS, running on an HP Elitebook 850 G2. Ubuntu is installed on an SSD, and I noticed that there were long delays that the hard drive light wasn't active. A check of dmesg showed two ~6 second delays in the boot process, both on the same problem:

After the hang, the boot proceeds as normal. Tried updating to the latest kernel (2.6.24-21-generic), but to no avail. Tried giving the switch "acpi=off" at bootup, laptop doesn't hang, but all ACPI related functions (standby, CPU throttling, etc) are removed. Tried updating BIOS, but it is already the latest version.
