Slow Boot, No SOUND, No Ethernet

[Mic Healey]

I would like to report the latest kernel update: 4.15.0.177.166 to my Linux Mint 19.1 systems displayed the following problems:

1. After Update - Boot process is VERY SLOW.
2. After Update - Once desktop comes up, mouse and keyboard are disabled for approx. 2 minutes.
3. All sound is totally disabled (gone) on the system and the device under Sound reports as "Dummy Output".
4. On another system with a USB-C to RJ45 Ethernet external connection dongle - the device was disabled, but could be re-detected, by removing and re-plugging into the USB-C port. This is not previously how it has operated.

After having these issues on multiple machines, I restored the system(s) to the previous kernel 4.15.0-176-generic with Timeshift without issue, correcting all issues listed above.

I believe this is a major issue(s) for the kernel and it's users and it needs to be addressed A.S.A.P.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1973234

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Unfortunately, this command at terminal yields:

mic@mic-Aspire-E5-576G:~$ apport-collect 1973234
ERROR: The python3-launchpadlib package is not installed. This functionality is not available.

When the machine is booted, open a terminal and run "dmesg" to see on what the kernel was stuck so long. In my case, it was the intel-lpss PCI device initialization, and I fixed it by disabling the Intel IOMMU. If you get similar results, this issue might be a duplicate of mine which I reported here:
