Hello, I bought a card which has an SK6805 LED onboard (https://www.tindie.com/products/hallard/ethtinfo-tic-teleinfo-reader-for-ethernet-esp32/) and I'm wondering if there is a way to control it from my BananaPI IO-8 ? Thanks

Thanks for links. I'm not concerned by AR-305 as I have an HDMI attached (It's my home automation dashboard, images you can see on my Twitter profile). But i don't have a SATA disk on this machine. The only google hits I found about this issue is related to disk access : as the only one I have is the SD card, I'm a bit fearing about its duration. But nothing is clear about this particular kworker : what is its goal ?

Hello, I'm running Armbian on the original (LeMaker) A20 powered BananaPI : cat /etc/issue Armbian 21.08.6 Buster \l I did an apt-get upgrade few days back, and since, it's CPU load is always around 1.00 even if I don't run my custom application (obviously, it wasn't the case before). Nothing special in /var/logs/messages, but top show me a kernel process always on top : top - 15:03:43 up 1 day, 17:40, 1 user, load average: 0,98, 1,03, 1,12 Tasks: 112 total, 2 running, 110 sleeping, 0 stopped, 0 zombie %Cpu(s): 4,5 us, 6,3 sy, 0,0 ni, 89,0 id, 0,0 wa, 0,0 hi, 0,2 si, 0,0 st MiB Mem : 993,9 total, 583,3 free, 119,7 used, 291,0 buff/cache MiB Swap: 497,0 total, 497,0 free, 0,0 used. 840,4 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26647 root 20 0 0 0 0 R 10,3 0,0 1:44.71 kworker/1:0+events_freezable_power_ 32375 laurent 20 0 103912 51264 5472 S 10,3 5,0 1:20.54 Selene 3664 laurent 20 0 7588 2372 2016 R 0,7 0,2 0:01.23 top 14 root 20 0 0 0 0 I 0,3 0,0 2:55.81 rcu_sched 1927 root 20 0 1408 336 292 S 0,3 0,0 10:37.20 BananaLEDd 31455 root 20 0 0 0 0 I 0,3 0,0 0:00.26 kworker/1:3-mm_percpu_wq I did some googling but it doesn't help to find out what is this events_freezable_power_ In another hand, it doesn't explain this 1.00 load as you can see it consums only 10 to 15% of the CPU as well as my own custom application. So any tip, help, whatever is welcome. Thanks
