I tested with Linux 4.0rc2. Without acpi=off, my system froze during the boot process. With acpi=off set, I was able to boot into X-Windows, log in, and start my web browser. Soon thereafter, however, my system froze up complete: mouse pointer did not respond, and no key combination provoked any response. I tried switching to a text console immediately after boot, which also resulted in a complete system freeze at some point. Note that even Alt+SysRq commands were non-responsive.
After leaving the system frozen for enough time (~5 minutes), it rebooted itself.
I'll be happy to provide whatever logs would be useful, just let me know what would help.
