NewDisplayName Posted March 17, 2018 Author Share Posted March 17, 2018 Seems to be known linux bug?! https://www.thomas-krenn.com/de/wiki/BUG_unable_to_handle_kernel_NULL_pointer_dereference_at_0000000000000304_beheben Quote Link to comment
trurl Posted March 17, 2018 Share Posted March 17, 2018 This doesn't look like a Defect Report (see guidelines sticky), and it also looks like you may be running the DVB version of unRAID, so even if it was a defect, it wouldn't be an unRAID defect unless you could reproduce it with stock unRAID. I will probably move this thread unless you edit the post to make it a defect report about stock unRAID. Quote Link to comment
NewDisplayName Posted March 17, 2018 Author Share Posted March 17, 2018 Hi, yes its the latest dvb version libreelec, i didnt know this makes a difference. Could you move it to correct thread? Quote Link to comment
CHBMB Posted March 17, 2018 Share Posted March 17, 2018 Hi, yes its the latest dvb version libreelec, i didnt know this makes a difference. Could you move it to correct thread?There's going to be nothing I can do about this. Suggest use stock and see if it resolves the issue. If it does then you've got two choices.EitherDowngrade to a DVB build without the issue or run current stock and see if the issue persists with the next release.Sent from my LG-H815 using Tapatalk Quote Link to comment
NewDisplayName Posted March 17, 2018 Author Share Posted March 17, 2018 I guess best is remove DVB and forget it. Its a shame that its "working" so baldy in 2018 (atleast the way i want to use it) Quote Link to comment
CHBMB Posted March 17, 2018 Share Posted March 17, 2018 I guess best is remove DVB and forget it. Its a shame that its "working" so baldy in 2018 (atleast the way i want to use it)DVB works fine as long as you pick your hardware carefully.Sent from my LG-H815 using Tapatalk Quote Link to comment
NewDisplayName Posted March 17, 2018 Author Share Posted March 17, 2018 No, or yes, i dont have hardware issues, its the software. I want 1 or 2 times a year TV streaming over plex (while on holiday). Plex integration is horror. Project seems dead to me. Quote Link to comment
BRiT Posted March 17, 2018 Share Posted March 17, 2018 Or use a network based DVB device that doesnt require device drivers in the kernel. Quote Link to comment

Plex integration is horror. Project seems dead to me.Well, yeah, Plex is a different matter. That is abysmal. I've been using DVB for the last 7-8 years, mostly on Linux since v5 of Unraid with TVheadend and it has been reliable. Occasionally you get the odd issue same with any software, but no complaints.Sent from my LG-H815 using Tapatalk Quote Link to comment
NewDisplayName Posted March 17, 2018 Author Share Posted March 17, 2018 Yeah im sure i could run other software instead of plex, but that was the whol ereason for it, to have verything in on app Quote Link to comment
