hop of those help? You're kernel seems to be pretty long. I suspect you are TDR'ing (timing out) out and Linux (Beignet) handles this more silently than Windows. Hence, I have a couple ideas.
Check dmesg for a TDR message. I haven't used Beignet or a Linux OpenCL implementation for that matter, but the Beignet documentation page (under "known issues") indicates you can check this via dmesg.

I hope this helps you . I don't know what it is, but i had the same problem when there was some *.cl file in my project. Just remove it from project (not from disk)! Anyway you will be able to read your source from this *.cl file, but when this file presents in project it causes en error. I don't know why.

I wish did fix the issue. I want to test a http get request. output something if timeout. , To set timeout use:
code :
http = Net::HTTP.new(host_param) 
http.read_timeout = 500

this one helps. I know this is kinda resurrecting an old thread, but I recently solved this problem and haven't found any solutions posted online, so here goes...
With the latest kernels rnodes is enabled by default, but this still doesn't work... Next step is to check the ownership of the /dev/dri files... e.g. on my system, I get:
code :
$ ls -l /dev/dri
total 0
crw-rw---- 1 root video 226,   0 May 16 21:30 card0
crw-rw---- 1 root video 226,  64 May 16 21:30 controlD64
crw-rw---- 1 root video 226, 128 May 16 21:30 renderD128
usermod -a -G video <user>

it helps some times Same problem happened to me. Then I figured that /dev/dri/card* access is only for the user root and the video group. You can run your application with sudo before the executable file. Good luck!
Side note: I added myself to the video group but it didn't work either. But it's working always fine with sudo command before the executable.
