how long should first boot take?

About half a minute and then it automatically reboots. If you have troubles I suggest that you try another SD card.

Can you explain this? Saying that doesn't help. Reason for this could be some mainline Kodi change, so I will never fix it, lot less searching for it. Generally, I don't see any stuttering, except in some rare cases with 23.976 fps video. If that is the case, I'm afraid you have to accept that or forever live with 20160203, which is actually not available for download anymore.

ofcourse 23,976fps , maybe i am too sensitive to any presentation glitches, unfortunately all movies have this framerate,

@Dima,

maybe this pull request will solve your LIRC issues: https://github.com/xbmc/xbmc/pull/9751/files

Can you test it?

Hello, I have Orange Pi Plus and I was using OpenElec for about half a year, but now I am not able to run latest images. The latest one that boots is H3.OPiPlus.arm-6.95.1 from 22.03.2016.
I've already tried precompiled images by Jernej and compile by myself but neither of them boots. Even the green led does not light up. I don't have the debug cable right now but if necessary I may get one to check why it does not boot. For me it looks like u-boot issue.

Do you also have Opi Plus and have the same issue?

I think I figured out what is the issue with suspend/resume:

Backported IR driver has no suspend/resume handling. I think this is your issue. Please confirm it with the next steps:
- connect serial console
- Enter this command:
  1. echo 8 > /proc/sys/kernel/printk
  Copy code
- trigger the bug
- Check if there is any crash/bug report in serial console. If it is, please post it here.
Deinterlace driver has very bad resume/suspend handling. While it would be easy to make a workaround in Kodi, I think it is better to fix kernel driver properly (I have an idea how and it is not so hard)
USB host driver has problems with hubs to which devices are attached. Can you or anybody else confirm this on OPiPC or One? This is the only reasonable explanation I could find. I finaly get crash report from kernel for this one. It was for usb1, which is connected to USB hub chip on OPi2 and Plus. It seems that something hangs and watchdog is triggered. Sometimes it is general watchdog and sometimes it is DPM (https://lwn.net/Articles/548967/). Currently, I am clueless how to debug/fix this (but then, I was also for deinterlace driver ).

Implementing suspend/resume for the first potential issue should also be relatively easy.

One more thing, why missing suspend/resume code in backported IR driver is problematic:
Arisc core on H3 has a special FW which waits for IR command to resume main ARM cores. So, when H3 goes into suspend, it reconfigures IR registers. If IR driver doesn't reconfigure registers back at resume, it simply can't work.

BTW, only NEC remotes are supported by arisc core. So whoever wants resume functionality with remote, NEC remote is requirement. I will test it once resume/suspend code is added.
