Thanks for the report. Can you check 6.2.0-34 from mantic-proposed? https://wiki.ubuntu.com/Testing/EnableProposed
If you don't want to enable proposed, here are direct download links: http://archive.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-6.2.0-34-generic_6.2.0-34.34_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-6.2.0-34-generic_6.2.0-34.34_amd64.deb If that doesn't help, could you try kernels between -26 (known good) and -32 (known bad) so we can narrow it down? http://archive.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-6.2.0-27-generic_6.2.0-27.28_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-6.2.0-27-generic_6.2.0-27.28_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-6.2.0-30-generic_6.2.0-30.30_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-6.2.0-30-generic_6.2.0-30.30_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-6.2.0-31-generic_6.2.0-31.31_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-6.2.0-31-generic_6.2.0-31.31_amd64.deb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.2 in Ubuntu. https://bugs.launchpad.net/bugs/2036988 Title: Unable to boot on Lenovo L590 Laptop Status in linux-signed-hwe-6.2 package in Ubuntu: New Bug description: With Kernel images 6.2.0-32 and 6.2.0-33, I can no longer boot ubuntu on my laptop. On regular graphic boot it just hangs on a black screen. With advanced boot options and selecting the current kernel, it hangs immediately after "Loading initial ramdisk" without any error message. I have to select an older kernel release to boot. 6.2.0-26 is the latest I know to work. We have another identical laptop of type Lenovo L590 also installed with Ubuntu and it shows the same behavior, so it's likely not a hardware problem on my device. The CPU type is Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz.
