[gentoo-user] my 5.15.93 kernel keeps rebooting
Hi. So, foolish me, I decided to go from a working 5.10.155 system to try latest lts of 5.15 which is 5.15.93. Compile, install went well, but the system keeps rebooting. It gets all the way and even starts the local services and then here are the last few lines, which may be relevant or not: Feb 14 06:36:31 ccs.covici.com systemd[1]: Starting local.service... Feb 14 06:36:31 ccs.covici.com systemd[1]: Starting systemd-update-utmp-runlevel.service... Feb 14 06:36:31 ccs.covici.com bash[5753]: rm: cannot remove '/etc/ppp/provider_is_up': No such file or directory Feb 14 06:36:31 ccs.covici.com systemd[1]: systemd-update-utmp-runlevel.service: Deactivated successfully. Feb 14 06:36:31 ccs.covici.com systemd[1]: Finished systemd-update-utmp-runlevel.service. -- Boot 5c394be675854680a9cb616208f374f3 -- Any trouble shooting suggestions as to what is making the system reboot?

This doesn't seem like a clean shutdown, so if it is a kernel PANIC I wouldn't expect the most critical info to be in the log (since it will stop syncing to protect the filesystem). The details you need probably will be displayed on the console briefly. You can also enable a network console, which will send the dmesg output continuously over UDP to another device. This won't be interrupted by a PANIC unless there is some issue with the hardware or networking stack. If you can get the final messages on dmesg and the panic core dump that would help. The other thing you can do is try to capture a kernel core dump, but that is a bit more complicated to set up. Otherwise your log is just going to say that everything was fine until it wasn't. -- Rich

OK, how would I set up logging to a network and what would I have to do on another computer -- which in my case is Windows? I do have a terminal program on there called teraterm which can do ssh, but that is about what I have -- unless there is some other program I can put on there. -- Your life is like a penny.

The docs are at: https://www.kernel.org/doc/Documentation/networking/netconsole.txt (you can also google for linux netconsole for some wiki articles on it) I have on my command line: netconsole=@/,@10.1.0.52 That IP is the host I want the log traffic to go to. (Read the docs if you have a more complicated networking setup - I assume that will just run ARP and send stuff out without using a gateway/etc.) Then on a receiving linux host I'd run (I think - it has been a while): nc -u -l -p Now, you mentioned Windows. I've never used it, but nmap has a program available in a windows version called ncat that might do the job: https://nmap.org/ncat/ You just want to make sure you have it listening on port for UDP. Make sure you use UDP or you won't receive anything. If it is working you should get a ton of log spam when your host boots - anything that shows up in dmesg will show up in the network console. It is sent in realtime. -- Rich

Sounds great -- I notice you ommitted the ip address, my network device is brought up by a systemd unit file, will I need to specify the device, then? I was thinking of netconsole=@192.168.0.1/eno1 -- would this be correct, assuming the ip address is correct? -- Your life is like a penny. You're going to lose it.

You're missing a lot of manual busy work you would have to do maintaining a package.provided since packages depend on stuff in that category.

After thoroughly reading the docs at... https://www.gentoo.org/support/news-items/2022-12-27-alternatives-introduction.html it looks like the hand of him-who-must-not-be-named. Rather than provide special support for the 1% extreme edge cases, the remaining 99% of regular users will be dragged through the change. More bloat; and eselect is on the road to eventual deprecation. With that in mind, I don't really have any choice but to go along. I'll have to change my sig to include something about a fully functional linux on a 16 *MEGA*byte machine running X (Yes, I actually was doing that back in 2000)... sigh. -- I've seen things, you people wouldn't believe; Gopher, Netscape with frames, the first Browser Wars.
