| 00:05.05 | DocScrutinizer05 | the whole thing looks like a big fake. Look, 3D-printed ferrite toroid (maybe still plausible) but then a 2N3055 powered from **a 9V-block battery** to drive two 'LAMP' which are at least LED 1W each |
| 00:06.05 | DocScrutinizer05 | prolly the electronic circuit in the LED lamps just works with 9V and the whole circuit is a big fake ;-P |
| 00:07.31 | DocScrutinizer05 | see http://laserhacker.com/?p=527 |
| 00:10.40 | DocScrutinizer05 | then WHAT THE FUCK?! he places a coaxial coil (another torus) into the hollow ferrite torus??? |
| 00:11.38 | DocScrutinizer05 | https://youtu.be/M9Hn5sfMH1Q?t=127 BULLSHIIIIIT |
| 00:14.13 | DocScrutinizer05 | ok, you _can_ do this, but... |
| 00:18.00 | DocScrutinizer05 | HAHAHAHA, I just thought what gonna happen when they reversed the battery, so C becomes E and E becomes C. Circuit looks way better then ;-P |
| 00:19.03 | DocScrutinizer05 | but still will fry the transistor from way too high reverse U_be |
| 00:20.19 | DocScrutinizer05 | no friggin idea what's going on, I guess the circuit diagram is plain wrong |

| 01:55.47 | kyak | damnit.. top and iotop show nothing, and still i get 0.5 LA. |
| 01:56.31 | kyak | i know a reboot would help, but this time i want to figure out what's going on |
| 01:57.27 | kyak | killing all heavy-weight suspects, like postgresql, still nothing |
| 01:59.21 | kyak | i noticed it is related to kernel upgrades not folowed by a reboot |
| 01:59.52 | kyak | on Arch Linux, kernel files are upgraded in-place.. although i don't understand how this can be aproblem for already loaded modules |
| 02:05.04 | DocScrutinizer05 | zticky topic |
| 02:05.11 | DocScrutinizer05 | tr* |
| 02:05.26 | wpwrak | kyak: embrace the reboot. don't fight it, my son. |
| 02:06.59 | kyak | --) |
| 02:07.45 | kyak | i'll be stripping down this system from running processes till it dies |
| 02:08.04 | kyak | when nothing is left, then it's the kernel |
| 02:09.13 | kyak | LA strangely starts at 00:00, but the temperature readings don't correlate |
| 02:09.26 | kyak | can kernel report LA incorrectly? |
| 02:10.25 | kyak | http://imgur.com/a/h5ads |
| 02:10.49 | kyak | ignore the high load in the middle of the day, i was doing things |
| 02:11.04 | kyak | these periodic peaks are also fine, i know what this is |
| 02:11.59 | wpwrak | load average can/could have a high constant offset if there are processes that want to run but are stuck somewhere |
| 02:12.24 | wpwrak | i had that happen with NFS. not sure if the calculation is still the same, though |
| 02:12.31 | kyak | how these processes will exhibit themselves in top? |
| 02:12.58 | kyak | i don't nfs, but have smb mounted.. let's try unmounting that |
| 02:13.36 | wpwrak | there may be unusual flags in STAT of ps aux |
| 02:14.04 | wpwrak | (unmount) if you can ;-) |
| 02:15.13 | kyak | you nailed it! it was a stall smb mount (remote host is not available) |
| 02:15.54 | wpwrak | heh :) |
| 02:15.55 | kyak | yeah, that's it.. Thanks! |
| 02:48.15 | DocScrutinizer05 | LA? |
| 02:50.23 | DocScrutinizer05 | err yes, I see lsysguard report bogus crap for basically all values based on /proc/* (the latter my suspicion), after a while since start of the monitor. I rend to blame systemd and the crap with cgroups and mounts it does |
| 02:50.38 | DocScrutinizer05 | ksysguard that is |
| 02:54.31 | DocScrutinizer05 | and a 2nd yes: processes idling in kernel IO can add to load while not using any CPU cycles. No idea where to spot them, iotop maybe |
| 02:54.50 | DocScrutinizer05 | or "wchan" in top |
| 02:56.19 | kyak | yeah, it's hard to spot those.. Especially because this is not a process, but a kernel thread, like in my case of samba mount |
| 02:56.32 | kyak | it just didn't reveal itself in iotop |
| 02:58.38 | DocScrutinizer05 | (kernel thread) haha, particularly nasty, yes |
| 02:59.23 | DocScrutinizer05 | yeah, prolly kswapd etc would be able to create similar shite |
| 03:03.37 | DocScrutinizer05 | http://paste.opensuse.org/61614886 pstree 2 |
| 03:04.28 | DocScrutinizer05 | filesystems via USB are particularly nasty regarding this, can freeze complete system |
| 03:11.26 | DocScrutinizer05 | F U systemd, wchan does only show "-" in htop |
| 03:13.48 | DocScrutinizer05 | nfc, maybe my htop is bitrotten |
| 03:13.54 | DocScrutinizer05 | ps -l works |
| 03:15.44 | DocScrutinizer05 | top also works |
| 03:16.03 | DocScrutinizer05 | might be the cold I caught |
