ACPI error after updating to the new 4.14 Kernel - T1125P - 12-10-2017
Hi all, I have encountered this error now when my E6330 is booting up. It was so fast I almost missed it. ACPI error. I have found a way to turn it off by editing the grub file. By doing do I disabled my laptop touch pad and mouse functions. So I had to use an external mouse to undo what I did. It's not affecting the way the laptop boots or functions just wondering if there is a way to remove that error notice.
Thanks

This might help:

If you do not need the newer kernel then it would be wise to go back to one that worked. The problem with going to far up the kernel chain is that the higher the kernel number the newer the hardware it only supports. I had all sorts of issues with the 4.13 and higher on this old laptop but staying at 4.10 series works fine. Please tell what addition to the grub.conf you did that threw the errors and disables your mouse and touchpad.

Thanks supergamer, reason I went to 4.14 was because the older Kernel, not sure which one 4.10? did not support USB 3.0 speeds. The exact command line that I touched was:
GRUB_CMDLINE_LINUX="" When I added apci=off between the "" that's what caused the touch pad and mouse to stop working. I can also confirm that Kernels 4.11 - 4.14 have the same issue.

Just out of curiosity try acpi=ht

Thanks I'll try that.

Same thing, who knows maybe with the next Kernel updates it will be cleared up.
