Hello guys!

I got my Opi in the last week. But I'm really disappointed. I read loboris' articles to ...

Maybe your keyboard requires too much power for the USB hub. Gaming keyboards will have this issue.

You should first do a google search for 'xfs arm bug' to get the idea what might happen with enabled XFS. And then it's time to rebuild the kernel:

I fear you're planning to use these settings for your 'NAS distribution'? Bad idea. Really bad idea.

Why bad idea? I do not understand why enabled xfs is a bad idea.
Thanks for the link options ;)

Maybe because neither data loss nor data corruption are that great? Here's another link: http://lmgtfy.com/?q=xfs+arm+bug

Also, the ARM compiler chain is suspect - we've got evidence that gcc from 4.6 through to 4.9 miscompile various different bits of XFS code (kernel and userspace) due to a combination of bad optimisations and broken (and unfixed) kernel asm code (e.g. the do_div() implementation).

IOWs, it's not a good investment in time to be chasing ARM specific XFS corruptions until the known problems with the toolchain and platform support are fixed up first.

And now guess what? The compiler you're using is a scruffy 4.6:

1. root@opennms:~# /var/git/H3/OrangePI-Kernel/brandy/gcc-linaro/arm-linux-gnueabi/bin/gcc --version
   
2. gcc (crosstool-NG linaro-1.13.1-2012.02-20120222 - Linaro GCC 2012.02) 4.6.3 20120201 (prerelease)

Copy code

While choosing XFS on big iron is sometimes a good idea (when using Mainline kernel I would always prefer btrfs/zfs these days) it's a really bad choice in your environment. And since you provide an OMV distributions the data of users relying on your work is at high risk. Please stop including dangerous 'features'!

I'm having a small problem here. I'm using an Arduino connected to /dev/ttyS2 so i can get some remote sensors. All works decently unless i'm actively using smbd. As this orange pi PC is doubling as a DB and my media server i'm trying to get to the bottom of this.

If the PI PC is idle uart2 works as it should (im using python to collect data). If i'm streaming something using smbd (cpu never goes higher than 0.50) uart2 just stops receiving data. I tried directly connecting to uart2 via minicom and screen and the data simply stops coming.

I tried to use one of the other ports, but are the apparently disabled in the latest kernel ?
