Currently running Linux Mint 17.3 (XFCE) on the Acer Aspire E5-511-PO1P laptop. Removed the work around above. Changed 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=dw_dmac,dw_dmac_core" back to "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" which was the original. Just upgraded the kernel from default 3.19 to 4.5 and have now rebooted the laptop 5 times with no issues so far. Seems the issue may of been fixed. Hope this helps.
