I am not terribly familiar with the git and make commands so I want to give a full account of my process in case I did something wrong.
First, I can confirm that 5.12-rc8 is the last kernel that doesn't work for me and 5.13-rc2 is the first one that does. I am skipping over 5.13-rc1 because I don't believe I can install it on my machine. It doesn't seem to be compatible with my Nvidia drivers as per this error: ERROR (dkms apport): kernel package linux-headers-5.13.0-051300rc1-generic is not supported Error! Bad return status for module build on kernel: 5.13.0-051300rc1-generic (x86_64) Consult /var/lib/dkms/nvidia/460.73.01/build/make.log for more information. Maybe I am just unwilling to mess with drivers enough to make it work, though. As for the bisect, I ran 'apt build-dep linux' (after checking 'Source Code' in Software and Updates so I could actually find the right packages) and cloned the git repository. Using 5.12-rc8 as the last non-working kernel and 5.13-rc2 as the first working kernel, I ran: cd linux git bisect start git bisect good v5.13-rc2 git bisect bad v5.12-rc8 This simply returned: Bisecting: a merge base must be tested [bf05bf16c76bb44ab5156223e1e58e26dfe30a88] Linux 5.12-rc8 which I didn't find particularly helpful. I had to use 'good' and 'bad' instead of 'new' and 'old' because the latter returned '[a string of numbers] is both old and new', which seemed wrong. To build the new kernel, I ran: make olddefconfig make localmodconfig make -j`nproc` deb-pkg This gave several warnings, but seemed to run OK. I can attached a file with the outputs if you want. It looks like it just built 5.12-rc8, although maybe the file name is misleading. I assume to install this kernel I should install the four .deb that make made: linux-headers-5.12.0-rc8_5.12.0-rc8-1_amd64.deb linux-image-5.12.0-rc8_5.12.0-rc8-1_amd64.deb linux-image-5.12.0-rc8-dbg_5.12.0-rc8-1_amd64.deb linux-libc-dev_5.12.0-rc8-1_amd64.deb I will do that when I have some time to test the new kernel unless I hear from you first. Hopefully, I did everything right. -- 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/1925843 Title: Linux 5.8.0-49+ fails to resume from suspend Status in linux package in Ubuntu: Incomplete Bug description: Expected Result: System resumes from suspend and displays the log in screen to unlock the computer. Actual Result: System displays a black screen with a flashing cursor in the upper left and cannot be interacted with. Hard reboot is required to get back to a working system. Additional information: When I boot my computer with 5.8.0-48, the system resumes from suspend as expected. Both 5.8.0-49 and 5.8.0-50 fail to resume from suspend. This problem began after I updated from 20.04 to 20.10 using the Software Updater on 4-19-21. I was using the latest kernel available for 20.04 at that time (5.8.0-48, I think) before updating.
