Ubuntu 22.04.3 fails to boot with Linux Kernel 6.2.0-32-generic

[Eliastik]

My Ubuntu installation fails to boot with the kernel 6.2.0-32-generic on a Lenovo Ideapad Flex 5 14ALC05

The Ubuntu splash screen appear with the loader but the boot process is stuck there (with the loader still animating)

No problem when booting with the kernel 6.2.0-26-generic

Status changed to 'Confirmed' because the bug affects multiple users.

Have the same issue with this kernel version 6.2.0-32-generic. Yesterday tried to boot in recovery mode, then i could see some messages that the kernel tried to connect to partitions e.g. /home that should be mounted but failed to connect to. Today the boot process already stuck after USB devices were detected.

Last kernel works fine!

Facing an issue with the same kernel on Dell G15.
Not able to boot even in recovery mode.

I was able to use this kernel version, but it started getting stuck after I installed Nvidia's CUDA drivers. Not sure if they are at all connected.

An update to this bug.
In the meantime a newer kernel version 6.2.0-33-generic is available, so i've installed it via "apt update / apt upgrade". Unfortunately it shows the same behaviour as the 6.2.0.32 version. So it's not possible to boot this notebook with the newer kernel versions.

Additional info:
For some testings i've added 2 partitions on the notebook and installed kubuntu 22.04.02 and as well from latest image kubuntu 22.04.3. (Only minimal system and with and without third-party drivers) All installations work fine after installation, but when i do an apt upgrade the 6.2.0-33-generic kernel will not boot.

Not sure if this is maybe interesting:
As in my initial installation the 6.2.0-31-generic kernel is working fine, i've tried to install this kernel on the test installations as well. Normal boot with the kernel 6.2.0.31 does NOT work! But in recovery mode it reaches the screen were you can select "resume" to proceed with boot. The last one works then, only e.g. network is missing.

Btw. I have another but old notebook ( from 2016 ), here everything works fine with this kernels.

[Michael Gödderz (goedderzm)]

As the kernel version that has the issue does not boot, the commands as per https://wiki.ubuntu.com/Kernel/Bugs
were collected with an older kernel!

Update.
After last "apt upgrade" and kernel 6.2.0-37-generic everything is working fine on my notebook.

I can confirm, the last update also fixed the issue on my laptop.
