NVIDIA – New Driver 346.35, Still Fails with 3.19-rc..

Adventures With Linux ™ Posted on by

Tested the lates NVIDIA driver (346.35) today, and although it fixes the f_dentry error, the compile still fails with Kernel 3.19-rc4, due to the incompatible GPL problem: FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ /usr/src/linux-3.19-rc4/scripts/Makefile.modpost:90: recipe for target ‘__modpost’ failed It has been pointed out that this can be fixed by simply changing the license … Continue reading →

Kernel 3.19-rc4 – OK on CuBox-i4 Pro.. No fixes yet for NVIDIA and VMware on x86..

Adventures With Linux ™ Posted on by

Updated the test system to Kernel 3.19-rc4, and the same comments apply as for -rc3..  Still no fixes for NVIDIA and VMware, yet.. I tried the CuBox-i4 Pro with a ‘standard’ kernel from kernel.org, rather than the ‘patched’ version used previously, and it booted OK.. Fedora release 21 (Twenty One) Kernel 3.19.0-rc4 on an armv7l (ttymxc0) …………. … Continue reading →

Adventures With Linux ™ Posted on by

Updated the test system to Kernel 3.19-rc3, and there is still no fix for VMware (11.0) and the latest NVIDIA (340.65 and 346.22) drivers…     The NVIDIA problem will involve getting around a GPL-incompatible module issue.. FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ 3.19-rc3 installs and runs OK on the CuBox-i4 Pro: $ uname -a Linux … Continue reading →

ARM/Intel – CuBox-i4 Pro to 3.19-rc2, VMware and NVIDIA Still Broken..

Adventures With Linux ™ Posted on by

Updated the test (Intel) system, and the Cubox-i4 Pro to Kernel 3.19-rc2.. NVIDIA and VMware still do not compile (see 3.19-rc1 article for details https://rglinuxtech.com/?p=1258) and – so far – there does not seem to be a patch for either.   The NVIDIA GPL code incompatibility issue may be more convoluted to fix ‘legally’.. I tried more code … Continue reading →

Just updated the Cubox-i4Pro to 3.19-rc1, after disabling the kernel options for ‘power management’, as the current patch does not compile cleanly..

Adventures With Linux ™ Posted on by

Yet another ‘lockup’ – this time with 3.18..    So, as the problem also exists with 3.17.x, I have taken the unusual step of reverting to Kernel 3.16.7, for the time being! Some of the latest correspondence on the issue, here:  http://lkml.iu.edu/hypermail/linux/kernel/1412.1/03302.html Robert Gadsdon.   December 12, 2014. … Continue reading →
