Adventures With Linux ™ Posted on by

More on the Kernel 4.14.9 NVIDIA breakage..     Basically, code that should have only gone into 4.15-rc found its way into 4.14.9 – which is why the existing 4.15 NVIDIA patch fixed it..     Thanks to dinosaur_ on the NVIDIA forum, there is a simpler patch available:  https://devtalk.nvidia.com/default/topic/1028016/linux/patch-for-compiling-v384-98-modules-with-linux-v4-14-9-/ There is also a 4.14.10-rc1 patch which is supposed to revert … Continue reading →

Adventures With Linux ™ Posted on by

Just updated to Kernel 4.14.9, and normally this should not be anything to cause concern, but this time there has been a significant code change made, that has broken NVIDIA (384.98): ………………… /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-384.98/kernel/nvidia-uvm/uvm8_va_block.c: In function ‘block_cpu_fault_locked’: /usr/src/linux-4.14.9/arch/x86/include/asm/processor.h:826:39: error: implicit declaration of function ‘task_stack_page’; did you mean ‘task_stack_vm_area’?

Just updated to VMware Workstation 14.1.0, and release notes are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/14.0.0/rn/workstation-141-release-notes.html This now works OK with Kernel 4.14 (tested with 4.14.8) but vmmon is still broken with Kernel 4.15 (tested with 4.15-rc4): ……………. /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c: In function ‘HostIF_InitUptime’: /tmp/modconfig-04hK9s/vmmon-only/linux/hostif.c:1770:4: error: implicit declaration of function ‘init_timer’; did you mean ‘init_timers’?

ARM64 – Fedora 27, UEFI and Pi3..

Adventures With Linux ™ Posted on by

I decided – after some time – to do some more with the Raspberry Pi 3, and set it up as a small network print server.. As there was now an ‘official’ version of Fedora 27 for the Pi3, I decided to use this..   Details are here, and links to aarch64 images are near the bottom of … Continue reading →

Just updated the test system to Kernel 4.15-rc3, and the GPL issue for NVIDIA drivers has been fixed, as mentioned – vaguely – in the brief details here:  http://lkml.iu.edu/hypermail/linux/kernel/1712.1/01379.html.

IA64 – Update to Kernel 4.15-rc1..

Adventures With Linux ™ Posted on by

Just updated the Itanium2 system (RX2600/ZX9000 hybrid) to kernel 4.15-rc1, but encountered a problem with the NFSv4 code.    Recent changes have exposed problems with ‘older’ compilers, and the system currently has GCC 4.3 (on Fedora 9/IA64): …………………..

NVIDIA – Another GPL Problem, but only with AMD Systems..

Adventures With Linux ™ Posted on by

Thanks to Pete for finding this one… There is another GPL-only issue with NVIDIA and Kernel 4.14-rc2, but this one only occurs if you have an AMD system, with the new ‘secure memory encryption’ feature enabled…    It may also crop up if you are using a Distro-created version of this kernel release, as these tend to have … Continue reading →

Adventures With Linux ™ Posted on by

VMware Workstation Pro 14.0.0 has been released – a bit earlier than expected – and it has a (potentially) nasty surprise for those with ‘older’ CPUs..   Release notes are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/14.0.0/rn/workstation-14-release-notes.html I installed this on my test system without any problems, and was able to confirm that it compiles and loads/runs OK with Kernels 4.13.x, and that … Continue reading →

Intel – Fix for Atom MMC/GPT warning..

Adventures With Linux ™ Posted on by

I had been getting a warning on boot with recent kernels on my Intel Atom-based UP system, and found a workaround..    The error flagged is – apparently – harmless, and is due to systemd not being able to recognise some mmc disk partitions at that stage of the boot process.. …… [ 5.124250] systemd-gpt-auto-generator[416]: Failed to dissect: … Continue reading →
