| sparr | I'm experiencing a kernel bug(?) causing cpu cores to soft lock one at a time. I can't open new web browser tabs right now, but I can run w3m. I'd like to possibly collect any useful info about the bug, and also figure out how to install a newer kernel than 4.19 | 00:06 |
|---|---|---|
| tomreyn | ubuntu-bug linux helps you collect logs and post a bug report | 00:19 |
| sparr | I managed to upgrade to a mainline kernel. If the problem doesn't recur then I doubt I'll need to submit a bug. if it does, I'll go back to the latest supported kernel and report it. | 00:34 |
| tomreyn | reporting a bug using the standard kernel could ensure it gets fixed, others benefit from the fix, have a better out of the box experience than you. | 00:44 |
| tomreyn | but it's a matter of how much you believe in communities helping each other. | 00:44 |
| sparr | if it's already fixed in the new kernel, would my report make a differnce in whether or not the fix is backported? | 00:47 |
| hggdh | sparr: yes. It will all depend on which kernel version added the bug, and which one corrected it | 00:50 |
| sparr | at the very least I'll test with whatever kernel ships with disco | 00:52 |
| Bashing-om | !info linux-image-generic disco | sparr | 00:53 |
| ubottu | sparr: linux-image-generic (source: linux-meta): Generic Linux kernel image. In component main, is optional. Version 4.19.0.12.13 (disco), package size 2 kB, installed size 15 kB | 00:53 |
| sparr | yeah, that's the one I was experiencing the bug on earlier, I think | 00:55 |
| sparr | definitely 4.19.0-12, not sure about the .13? | 00:56 |
| sparr | "systemd[1]: unattended-upgrades.service: Succeeded." <-- would this explain why my machine just spontaneously rebooted? | 04:36 |
| sparr | hopefully unrelatedly... something I've done today has led to powertop being terminated by "SIGSEGV (Address boundary error)" almost immediately after starting, before it displays any results. I don't even know how to troubleshoot that. | 05:02 |
| sparr | I got powertop to give me a core dump, but unfortunately it's compiled without debugging symbols | 07:57 |
| === lotuspsychje_ is now known as lotuspsychje | ||
| tomreyn | sparr: there is powertop-dbg | 18:52 |
| sparr | I compiled with debugging symbols myself, collected some data, am now out of ideas / gdb-fu | 18:53 |
| sparr | but it's on a mainline kernel, so I'm seeking help elsewhere | 18:54 |
