Kernel 3.18 – and 3.17 – Beware of Lockups..

Adventures With Linux ™ Posted on November 29, 2014 by RGNovember 29, 2014

A problem that still plagued the 3.18-rc series of kernel releases now seems to affect 3.17 as well.. I have had two complete system hangs with 3.17.3 and 3.17.4 on my main system in the last two weeks, and thought at first that these were caused by KDE and/or NVIDIA hangs, but then found that I could … Continue reading →

Adventures With Linux ™ Posted on November 10, 2014 by RGNovember 10, 2014

Just installed the kernel.org version of kernel 3.18-rc4 on the Odroid U3, and this time it completed the boot, but still had a ‘tombstone’: …………… cam-power-domain: Power-on latency exceeded, new value 413333 ns cam-power-domain: Power-on latency exceeded, new value 564291 ns Unable to handle kernel NULL pointer dereference at virtual address 00000010 pgd = ee328000 [00000010] *pgd=00000000 … Continue reading →

ARM – Odroid Kernel 3.17/3.18 USB Solution..

Adventures With Linux ™ Posted on November 8, 2014 by RGNovember 8, 2014

I had been trying to get USB working with 3.17 and 3.18-rc kernels on my Odroid U3 for some time, and had been looking for fixes in the source code. It turned out that I was looking in the wrong place – and a clue to this was the lack of any mention of the problem on … Continue reading →

Kernel 3.18-rc3 – Boots OK with ‘new’ .config..

Adventures With Linux ™ Posted on November 4, 2014 by RGNovember 4, 2014

Tested Kernel 3.18-rc3 and found that it would not boot with the .config that worked OK with -rc1..    Re-created a new .config from scratch, and now my temporary test system (HP6830 laptop) boots OK, but overall performance still seems rather sluggish.. # uname -a Linux rg6830l 3.18.0-rc3 #1 SMP PREEMPT Mon Nov 3 18:19:06 PST 2014 x86_64 … Continue reading →

Kernel 3.18-rc2 – Best to Wait for -rc3?

Adventures With Linux ™ Posted on October 29, 2014 by RGOctober 29, 2014

An unusual experience with testing Kernel 3.18-rc2, as it actually failed to boot on my test system!     Config was the same as the one that booted OK on -rc1, but this time the system can’t find the root disk…. [    OK   ]  Reached target Basic System [ ***    ]  (1 of 3) A start job is running … Continue reading →

Kernel 3.18-rc1 – NVIDIA Fix..

Adventures With Linux ™ Posted on October 21, 2014 by RGOctober 21, 2014

Thanks to juston_li, there is a one-line fix to enable the latest NVIDIA drivers to compile with Kernel 3.18-rc1 See: https://devtalk.nvidia.com/default/topic/783364/linux/343-22-driver-incompatible-with-linux-3-18-/ The fix there is for Beta version 343.22, but I applied it to main version 340.46, as follows: In NVIDIA-Linux-x86_64-340.46/kernel/nv-drm.c , at line 19, change #if defined(NV_DRM_AVAILABLE) #include <drm/drmP.h> to #if defined(NV_DRM_AVAILABLE) #include <drm/drmP.h> #include <drm/drm_gem.h> … Continue reading →

ARM – Odroid U2 – Finally an Up-to-Date Kernel?

Adventures With Linux ™ Posted on September 12, 2014 by RGSeptember 12, 2014

I had been frustrated by the apparent inability of the suppliers to provide anything other than an obsolete Ubuntu-centric 3.8+ kernel for the Odroid U2, and other kernels I had tested were somewhat ‘incomplete’… I finally managed to get a 3.17-r3 version from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.17.y This now includes the necessary ‘bits’ for the U3, which is functionally identical … Continue reading →
