Issue Description

<Describe your issue / question / feature request / etc..> I had installed the SDK on Intel NUC ,just only followed steps here https://github.com/IntelRealSense/librealsense/blob/development/doc/installation.md .The error never showed when I installed on my own PC. When I installed it at the last step ./scripts/patch-realsense-ubuntu-xenial.sh the error showed as below: Patched kernels modules were created successfully

Handle videodev : Applying the patched module ... modprobe: ERROR: could not insert 'videodev': Exec format error Failed to insert the patched module. Operation is aborted, the original module is restored Verify that the current kernel version is aligned to the patched module version The original videodev module was reloaded

Anybody know why? Please help me with this problem.Did it because the platform change?

ev-mp commented 6 years ago

Hello @GITSHOHOKU , the error may indicate that the patched module kernel was build for a version different from the currently loaded kernel. Make sure to follow the instructions and update Ubuntu before applying the kernel patch.

Additionally, please provide the following data:

uname -r
dmesg output after the patch script completes.

GITSHOHOKU commented 6 years ago

I tried it again and I am sure I follow the step to update ubuntu ,

when I ran uname -r I got Patched kernels modules were created successfully

GITSHOHOKU commented 6 years ago

the problem seems to be indicated by this line _videodev: version magic '4.4.0-116-generic SMP mod_unload modversions ' should be '4.4.0-116-generic SMP mod_unload modversions retpoline '_ but I don't know where is wrong because I do update my Ubuntu

ev-mp commented 6 years ago

Hello @GITSHOHOKU , I was not able to reproduce the error with two 4.4.0-116-kernel based desktops, but then I found this link that indicates that some previous decision in Linux tree was reverted and a patch has been removed from the kernel tree (see this for kernel 4.4). Apparently the change in vermagic string - 4.4.0-116-generic SMP mod_unload modversions instead of 4.4.0-116-generic SMP mod_unload modversions retpoline (Note the last word removed) did not propagate to Ubuntu distro yet, but did reach the source code tree. Hence the generated error.

I will work to establish a repro environment and update the thread when the fix is set.

In the meanwhile the alternatives are: 1 - Use librealsense DKMS package to install kernel patches:

sudo apt-get install realsense-uvcvideo

Switch to another supported LTS kernel, 4.10 or 4.13, and reapply the patch.

ev-mp commented 6 years ago

Hello @GITSHOHOKU , the warning you receive is a known issues as DKMS tries to install both for 4.4 and 4.10 kernels, (and fails for 4.10, which is not current). We are currently testing an updated DKMS that will remove this inconvenience. But the DKMS for 4.4 would be installed by then. To verify that it is installed properly please proceed according to DKMS installation check-list:

Complete the installation by performing reboot to reload the kernel with modules provided by DKMS. Verify that the kernel is updated : modinfo uvcvideo | grep "version:" should include realsense string

Then run realsense-viewer tool to stream depth/infrared and update

GITSHOHOKU commented 6 years ago

Thanks for your help ev-mp. I didn't try after modinfo uvcvideo | grep "version:" should include realsense string shows 4.4.0 Then I changed my kernels to 4.10.0-28 (Ubuntu16.04) and follow the step when I patched module it shows `Patched kernels modules were created successfully
