ACPI native driver creating conflicts on 18.04

Asked by leon antoniadis on 2018-07-03

After the last update to 4.15.0-24-generic it takes ages to light up.
Running "dmesg | less" i came to a note "ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver". Going back to 4.15.0.-23 the laptop stars in 25 seconds.
Please advise

I suggest you report a bug

1. The message "ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver" alone does not tell anything. It usually is just a subsequent message to the meaningful one. And in any case I doubt that this is causing the delay.

2. If you see long boot times, you should check the syslog for big gaps in the time code.

As situation was unbearable considering it is a laptop which is on/off continuously, far from ac mains, I purged 4.....-24 and
working with 4......-23 "solved" my problem.
Thanks.

Your problem perhaps was/is caused by Bug #1780062
There is already a new version of the kernel being prepared (4.15.0-26.28, already in bionic-proposed).
Hopefully this will bring boot times back to normal.
