Update: I downgraded my kernel to 6.8.0-31-generic on 2025/01/24, and I have since been crash-free. Since the bug only occurred every 2-3 days, I will go for a few more days to confirm the absence of crashes. If this holds up, the bug should be related to a change between versions 31 and 51 of the following packages:
linux-headers-6.8.0-31 linux-headers-6.8.0-31-generic linux-image-6.8.0-31-generic linux-modules-6.8.0-31-generic linux-modules-extra-6.8.0-31-generic linux-tools-6.8.0-31 linux-tools-6.8.0-31-generic -- 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/2096804 Title: Kernel crashes several times a week; no diagnostic information available Status in linux package in Ubuntu: New Bug description: After upgrading to Ubuntu 24.04, I frequently get a complete kernel stoppage. In the middle of doing any random task, the entire laptop freezes: no mouse movements, no Ctrl-Alt-F1, no Ctrl-Alt-Backspace, nothing. Whatever the last content of the screen was just remains there as a static image. Logs: There is nothing reported in /var/log/kern.log just prior to the crash; the system simply seems to stop in its tracks. There are no relevant messages in desg or syslog either. To reproduce: It doesn't seem to be triggered by what I am doing at the time, i.e., it occurs at random times. I assume the bug is in the kernel itself (linux- image-6.8.0-51-generic), or perhaps in a module, as nothing in userspace should create a complete shutdown. I realize this report doesn't do much to pinpoint the location of the bug; please advise on what I should do to collect more information. Thanks.
