Thank you for your suggestions. I tried every kernel in your list via direct deb download and none of them works. 6.2.0-26 is the latest that can boot on my device. 6.2.0-27 and later 6.2.0 releases do not boot.
Side note: When browsing the archive server, I found 6.5.0-6 and that one can boot up (but has other issues). -- 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.
