OK. I followed the above instructions and eventually managed to install the recommended firmware and kernel. Upon rebooting there were several console errors: [1.096562] Couldn't get size: 0x800e [1.700597] psmouse serio1: elantech: elantech_send_cmd query 0x02 failed. [1.700620] psmouse serio1: elantech: failed to query capabilities. Eventually the system booted. The USB mouse didn't work but the laptop's touch pad still functioned. Wireless network support appeared to be fine. I did not experience the problems that triggered this bug report.

And in the directory you had me check are only *.ko files. So I'm not sure what to replace with what here. Sorry, guys, but the last time I built my own kernel was on Slackware Linux 1.18 in 1994 (if memory serves) and the current structure and organization of the various kernel components is a little beyond me. I'm eager to do whatever you need me to do to provide you with the data you need in order to find out what the problem is, but I'm going to need a little bit of hand-holding here. Sorry to be a pain but I'm not at all sure how to proceed at this point to install the updated kernel and firmware modules you need me to try.

[Kernel-packages] [Bug 1830350] Re: System freezes repeatedly for several seconds; wifi driver related errors
@Kai-Heng Feng: I will do that. However, I'm deadlined right now and this is my production machine, so it'll have to wait for the paying job to be dealt with (probably this weekend). Two questions, though: 1. The latest linux-firmware that you directed me to (linux- firmware-20190514.tar.gz) is obviously intended for those who know what they're doing. It is just a matter of "make install"? Because pretty much all that does is copy the contents of the tarball to /lib/firmware and I don't think that's enough. 2. Can I simply install: linux-image-unsigned-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb linux-modules-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb linux-headers-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb or are there other dependencies as well that I need to be aware of / deal with? (As you will probably have understood by now I've little or no experience with nightly builds, interim development releases and/or other Linux development related issues.) Please advise.

[Kernel-packages] [Bug 1830350] Re: System freezes repeatedly for several seconds; wifi driver related errors
@Kai-Heng Feng: I will do that. However, I'm deadlined right now and this is my production machine, so it'll have to wait for the paying job to be dealt with. Two questions, though: 1. The latest linux-firmware that you directed me to (linux- firmware-20190514.tar.gz) is obviously intended for those who know what they're doing. It is just a matter of "make install" or is there more to installing this version? I'm a little concerned about hosing my system, seeing as it's my production machine. 2. Can I simply install: linux-image-unsigned-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb linux-modules-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb linux-headers-5.2.0-050200rc2-generic_5.2.0-050200rc2.201905262130_amd64.deb or are there other dependencies as well?

[Kernel-packages] [Bug 1830350] Re: System freezes repeatedly for several seconds; wifi driver related errors
@Kai-Heng Feng: Sorry, it took me a while to figure out how to do this. I have downgraded the linux-firmware package to 1.173 which is the only version I could find before 1.173.5. The problem started with the update to linux-firmware_1.173.5 and the regular update to 1.173.6 (which was the one running before the downgrade) did not resolve the issue. @lotuspshychje: I have not yet downgraded the kernel to a previous version. (Current version: 4.15.0-50-generic #54-Ubuntu SMP Mon May 6 18:46:08 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux, current package linux- generic 4.15.0.50.52). With the current kernel and the downgraded linux-firmware package the symptoms seem to have disappeared. This suggests that the issue is related to the linux-firmware package (starting at 1.173.5)rather than the kernel itself. (I expect the bug should be reclassified as applying to this package accordingly.) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1830350 Title: System freezes repeatedly for several seconds; wifi driver related errors Status in linux package in Ubuntu: Confirmed Bug description: I updated my system about a month ago (Fri 26 April 2019).

[Kernel-packages] [Bug 1830350] Re: System freezes repeatedly for several seconds; wifi driver related errors
According to the APT log (/var/log/apt/term.log*) the update on 26 April last installed the 4.15.0.47 kernel. This is when the problem started, so if this is exclusively kernel-related the problem is a change between 4.15.0.46 and 4.15.0.47. However, the only two kernel versions currently still available in the grub menu are 4.15.0.48 and 4.15.0.50. So I'm not sure how to revert to a pre-4.15.0.47 kernel. Is there a way to revert to an older kernel from the repositories?

The freezes last a few seconds. Keyboard input is preserved at this time and typed input appears after the freeze is resolved. Mouse cursor continues to move during freezes but mouse clicks are only processed after the freeze is resolved, i.e. the result of the mouse click is suspended (e.g. buffered) until the system becomes responsive again. For example, clicking on a window during the freeze will focus that window after the freeze has been resolved. The system is a Dell Inspiron 15 3576.

I reported the bug (maybe in the wrong place) but so far I have received no response. I've lived with this for a month or so hoping that further updates would fix the problem but it still persists. Installing the latest firmware update (14 Mar 2019) has no effect. No other changes were made to either hardware or OS configuration.
