disconnect

Hi If i boot my cubieboard2, sometimes it's visible on network, and reachable, sometimes not at all. After that, it isn't changes. No problem with the LAN cable, i've tried two. Also the speedtest shows the maximum bandwidths in both directions (~92 mbit/sec). The system boots always, as i see from logs. Here is from the log: sudo cat /var/log/messages | grep ether Feb 23 09:14:43 localhost kernel: [ 2.059648] sun7i-dwmac 1c50000.ethernet: PTP uses main clock Feb 23 09:14:43 localhost kernel: [ 2.059661] sun7i-dwmac 1c50000.ethernet: no reset control found Feb 23 09:14:43 localhost kernel: [ 2.059690] sun7i-dwmac 1c50000.ethernet: no regulator found Feb 23 09:14:43 localhost kernel: [ 2.059979] sun7i-dwmac 1c50000.ethernet: Version ID not available Feb 23 09:14:43 localhost kernel: [ 2.059991] sun7i-dwmac 1c50000.ethernet: DWMAC1000 Feb 23 09:14:43 localhost kernel: [ 2.059999] sun7i-dwmac 1c50000.ethernet: DMA HW capability register supported Feb 23 09:14:43 localhost kernel: [ 2.060006] sun7i-dwmac 1c50000.ethernet: Normal descriptors Feb 23 09:14:43 localhost kernel: [ 2.060012] sun7i-dwmac 1c50000.ethernet: Ring mode enabled Feb 23 09:14:44 localhost kernel: [ 10.408311] sun7i-dwmac 1c50000.ethernet eth0: device MAC address 86:98:a8:6e:1b:69 Feb 23 09:14:44 localhost kernel: [ 10.431624] sun7i-dwmac 1c50000.ethernet eth0: No Safety Features support found Feb 23 09:14:44 localhost kernel: [ 10.431638] sun7i-dwmac 1c50000.ethernet eth0: RX IPC Checksum Offload disabled Feb 23 09:14:44 localhost kernel: [ 10.431648] sun7i-dwmac 1c50000.ethernet eth0: No MAC Management Counters available Feb 23 09:14:44 localhost kernel: [ 10.431657] sun7i-dwmac 1c50000.ethernet eth0: PTP not supported by HW Feb 23 09:14:45 localhost kernel: [ 11.456229] sun7i-dwmac 1c50000.ethernet eth0: Link is Up -

Anyone sees something?

I've never had this problem, until i've updated to 4.19.13 kernel, with the update last sunday. Since that, 10% cpu in average eaten by kworker. ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.19.13-sunxi

Cubieboard2 becomes unreachable on ethernet if the switch to which the CB2 connected to is rebooted/powered off then on. Every other devices communicate after the restart, except CB2, it needs an on/off to make its networking work again. Why? It has fixed IP, and also set fixed mac address, but no luck. It runs the latest armbian (5.38), with mainline kernel

The power supply is the cubieboard2 itselft, with the included 5v+ sata cable.

Hi My cubie2 with a 2.5" HDD has exception Emask 0x10 SAct 0x80000 SErr 0x90300 action 0xe frozen [182296.803589] ata1.00: irq_stat 0x08400000, interface fatal error, PHY RDY changed [182296.803605] ata1: SError: { UnrecovData Persist PHYRdyChg 10B8B } [182296.803624] ata1.00: failed command: READ FPDMA QUEUED errors sometimes, which causes shutdown, spin up for HDD, with a big click sound, and it's not good for it. So i would try if it happens when the sata link is set to slower. But how can i do that?

It seems a restart solved this problem

Hi Few days ago i've upgraded by armbian to the newest release version 5.17? from 5.11. The problem is, that minidlna DLNA server is only visible for few minutes after the service is started. Later i need a restart the service to make it visible for the new clients. The strange is that when i don't exit/shutdown the client, after the server discovered, it stays visible and works perfectly. But i want to make it visible for a newly started client, i need to restart the service. It doesn't seem to be client problem, as the same happens with my samsung smart tv, and a windows pc with foobar 2000 dlna plugin. What's the problem? (it maybe a broadcasting problem)

Now with the patch which included in armbian 5.10 sunxi_ss seems to work correctly.

Should the update work now with apt-get upgrade? Because for me, apt-get update && apt-get upgrade does not lists available upgradeable packages.

There is a patch for sunxi_ss data corruption: https://lkml.org/lkml/2016/3/23/302 Can be included in 5.1?

Patch (workaround) for the problem: https://lkml.org/lkml/2016/3/23/302

other bug http://forum.armbian.com/index.php/topic/844-how-to-use-cubietruck-crypto-hardware-sunxi-ss/ however it seems it can't be fixed.

https://groups.google.com/forum/#!topic/linux-sunxi/InsDjSm3J6A probably when the developer gets an answer to this question: https://lkml.org/lkml/2016/3/13/64

did you checked alsamixer for muted outputs? By default all are muted.

If you want to use for disk encryption, then you should wait, as it's broken, and corrupts the files.
