Kernel – 4.11-rc1 and BTRFS – a Warning..?

Adventures With Linux ™ Posted on March 14, 2017 by RGMarch 14, 2017

I encountered a catastrophic problem with btrfs formatted system disk partition corruption, shortly after updating a test system to Kernel 4.11-rc1. To put this in context, this may be an isolated incident, and I have not seen problems – so far – mentioned elsewhere..    But.. there a quite a lot of BTRFS changes on 4.11, and – … Continue reading →

VMware – Patch for Kernel 4.11 Support..

Adventures With Linux ™ Posted on March 7, 2017 by RGMarch 7, 2017

Thanks to Virgo, there are now patches for vmnet and vmmon with Kernel 4.11 (see his comments under the earlier article).    These are incremental patches, for application to VMware 12.5.2 code already patched for Kernel 4.9/4.10 support.. Links are here:   http://pastebin.com/McqmUf0u     and    http://pastebin.com/yjbDHiSX I have modified these (adding appropriate #if LINUX_VERSION_CODE…… #endif statements) to be backward-compatible with … Continue reading →

NVIDIA – New Drivers, Still Broken with 4.10 – And a Patch for 378.13..

Adventures With Linux ™ Posted on February 15, 2017 by RGFebruary 15, 2017

NVIDIA have released new drivers 375.39 (‘long term’) and 378.13 (‘short term’) and details are here:  http://www.nvidia.com/download/driverResults.aspx/114708/en-us and http://www.nvidia.com/download/driverResults.aspx/115031/en-us. Both still fail to compile with Kernel 4.10 (tested with 4.10-rc8) and I tried the previous 378.09 patch against 379.13, but it failed to apply cleanly, as more code has changed.. $ cat nv-37809-410-patch.patch |patch -p0 patching file … Continue reading →

Thanks to Heiner Kallweit for info on two USB patches for the Odroid C2, and thanks to John Youn for the patches themselves..  They can be found at http://www.spinics.net/lists/linux-usb/msg151687.html and http://www.spinics.net/lists/linux-usb/msg151688.html . I have applied these to Kernel 4.10-rc4 (including the Ethernet TX patch) and now USB is working, and detects/connects devices – sort of.. Plug in … Continue reading →

ARM64 – Kernel 4.10-rc4 on Odroid C2 – Ethernet Still Needs DTS Patch..

Adventures With Linux ™ Posted on January 17, 2017 by RGJanuary 22, 2017

Just updated the Odroid C2 to Kernel 4.10-rc4, but the Ethernet hang problem still persists..   Applied the dts Ethernet TX patch (see http://rglinuxtech.com/?p=1872 ) , and it works OK now.. There seems to be a bit of a backlog of Meson/GXBB patches, and I read that the Ethernet TX fix was supposed to be merged with -rc4, … Continue reading →

ARM64 – Odroid C2 – Kernel 4.10-rc Config Example..

Adventures With Linux ™ Posted on January 15, 2017 by RGJanuary 15, 2017

As Odroid C2 support by the ‘mainline’ kernel is – hopefully – nearing completion, I have put a sample of my Kernel config at http://pastebin.com/XWfMEWHx . The C2 is used for ‘headless’ operation, at present, and USB still does not work..    The kernel is 4.10-rc3, with the ‘Ethernet-TX’ dts patch applied.. (see http://rglinuxtech.com/?p=1872 ).

ARM64 – Odroid C2 – Boots with Kernel 4.10-rc1 – Ethernet OK? – Not yet..

Adventures With Linux ™ Posted on December 26, 2016 by RGJanuary 15, 2017

After applying the aarch64 compile fix (see previous article) I was able to compile Kernel 4.10-rc1 on the Odroid C2, and it boots OK (headless..), and the Ethernet link stays up, but still needs the TX patch..   (updated, as the link did still hang – eventually..  RG).. ……….. meson8b-dwmac c9410000.ethernet eth0: Link is Up – 1Gbps/Full – … Continue reading →
