[00:06] <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
[00:19] <tomreyn> ubuntu-bug linux helps you collect logs and post a bug report
[00:34] <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.
[00:44] <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.
[00:47] <sparr> if it's already fixed in the new kernel, would my report make a differnce in whether or not the fix is backported?
[00:50] <hggdh> sparr: yes. It will all depend on which kernel version added the bug, and which one corrected it
[00:52] <sparr> at the very least I'll test with whatever kernel ships with disco
[00:53] <Bashing-om> !info linux-image-generic disco | sparr 
[00:55] <sparr> yeah, that's the one I was experiencing the bug on earlier, I think
[00:56] <sparr> definitely 4.19.0-12, not sure about the .13?
[04:36] <sparr> "systemd[1]: unattended-upgrades.service: Succeeded." <-- would this explain why my machine just spontaneously rebooted?
[05:02] <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.
[07:57] <sparr> I got powertop to give me a core dump, but unfortunately it's compiled without debugging symbols
[18:52] <tomreyn> sparr: there is powertop-dbg
[18:53] <sparr> I compiled with debugging symbols myself, collected some data, am now out of ideas / gdb-fu
[18:54] <sparr> but it's on a mainline kernel, so I'm seeking help elsewhere
