Kernel 3.13 in Linux VMware Guest – Shared Folders Problem

Adventures With Linux ™ Posted on by

Setting up a test system for the usb/uvcvideo tests, I have found another kernel 3.13 issue – this time with Linux as a VMware guest.. The shared folders – which work OK with 3.12, do not work with 3.13. Normally shared folders are found under /mnt/hgfs, but with 3.13 the hgfs directory is corrupted in some odd … Continue reading →

Back to 3.12.8..

Adventures With Linux ™ Posted on by

After some problems with uvcvideo / usb under 3.13 producing non-working camera and audio, and producing a ‘tombstone’, I have reverted to 3.12.8 for the time being..    More research is needed, and I have set up a 3.13 ‘guest’ under VMware to conduct further tests, without the ‘kernel taint’ of NVIDIA drivers, etc.. [50677.696508] cannot submit urb … Continue reading →

ARM: Fun with Device Trees…

Adventures With Linux ™ Posted on by

ARM devices on Linux are rapidly moving to use the ‘device tree‘ format to specify the CPU / SoC characteristics at kernel compile time, for producing the boot image…   For systems such as the DreamPlug, this means that the old # make uImage is no longer applicable.. For the DreamPlug, this is an example of the … Continue reading →

3.12.5 – Problems? – No..

Adventures With Linux ™ Posted on by

Just updated to Kernel 3.12.5, and quickly reverted to 3.12.4.. Update:   the problem turned out to be a badly-timed coincidental update to MariaDB (5.5.34)..   Reverting to the previous version (5.5.33a) fixed the problem..    Now running 3.12.5.. With 3.12.5, Avahi mDNS failed, and – more importantly – MariaDB would not start: mariadb.service – MariaDB database server    Loaded: … Continue reading →

NVIDIA – Run-Time Fix for 3.13..

Adventures With Linux ™ Posted on by

Although the latest NVIDIA drivers compile OK on kernel 3.13-rc1, they do not load/run correctly, and may only give low-res output… The same problem exists with the newest version just released – 319.76.. nvidia: Unknown symbol acpi_os_wait_events_complete (err 0) There is a fix available, in this thread from DevZone: https://devtalk.nvidia.com/default/topic/644906/331-20-on-3-13-rc1-kernel/ – but note the logic correction mentioned … Continue reading →
