I edited the topic title, long titles are often hard to read and also do not help with searching. You posted in the Support and Help category, therefore help needed is already implied.
I also removed parts of the template you did not use. Please refer to the guide on using and filling out the template for future reference.
Not clear to me what general recommendations are being referred to.
Please outline the steps you took, which commands you used/changed and if possible the source.
One suggestion to try would be to use a liveUSB of a newer version of Ubuntu such as 25.10 or even the current development release, 26.04, and test in the live environment whether or not you experience the same issues.
I would try the upcoming 26.04. I’m sure the new kernel 7.x will bring a lot of improvements for such hardware. Meanwhile make sure to update UEFI and also the drives’ firmware, if aplicable.
I think is for something else, Ubuntu being the host. Otherwise it wouldn’t make sense the last caomment about the issues with Virtualbox and VMware (BTW, solved already).
Exactly, I am running Ubuntu as the host for VMware Workstation and Virtualbox. Some of my colleagues prefer the one and some the other. That’s why I have both installed. If you need to use virtualization for your daily work then it’s a pain how often the Ubuntu desktop version changes the main kernel version. All the time you get the known problems if the kernel modules do not compile again. That’s why I’ve actually been thinking about whether I shouldn’t just install the server version of Ubuntu instead. That server version keeps the same main kernel version, right?
I’ve seen similar reports for the ZBook G9. Have you tried disabling ‘Extended Idle Power States’ in the BIOS (under Power Management)? Also, since it happens mostly on Wayland, try adding i915.enable_psr=0 to your Grub parameters. If it still freezes, check if journalctl shows any i2c_designware timeouts right at the moment of the freeze
