ARM64 – Pi3 64-Bit Tribulations.. Too Soon for Stability..

I had ordered a Raspberry Pi 3 back in March in the hope that it would be a useful exercise in 64-bit on a different chipset..    I was (somewhat) disappointed to find that there was no initial 64-bit support, and … Continue reading

Kernel – 4.2.1 – Still Breaks NVIDIA?

Tried the ‘release candidate’ version of Kernel 4.2.1 (via patch, at https://www.kernel.org/pub/linux/kernel/v4.x/stable-review), and the GPL_only issue with NVIDIA drivers is still there…      Exactly why we have to wait for Kernel 4.3 for this to be fixed is a mystery, as … Continue reading

ARM – Odroid U3 test with Kernel.org 4.0-rc3 – Panic..

As there is no later version of the Odroid-specific 4.0 kernel source available yet, I decided to test with the standard 4.0-rc3 from kernel.org, but the U3 booted – and then Panic‘d.. ……………………….. EXT4-fs (mmcblk0p3): mounted filesystem with ordered data … Continue reading

NVIDIA – New Driver – Kernel 3.13 Fail..

NVIDIA have just released driver 334.16, but – despite the fact that Kernel 3.13 has been released for some time now – the driver still fails to load correctly, with the same ”Unknown symbol acpi_os_wait_events_complete (err 0)” error.. So, the … Continue reading

NVIDIA – Epic Fail?

I had assumed that my previous article on ‘auto patching’ was going to be redundant…    However, I discovered to my dismay that even the newly-released NVIDIA driver – 331.17 still fails to compile and install on 3.11 and 3.12 kernels.. … Continue reading

3.9-rc7 Released, NVIDIA and VMware OK..

Just installed kernel 3.9-rc7 on my test system, and VMware (9.02) and the latest NVIDIA ‘stable’ (310.44) and ‘beta’ (319.12) drivers all compile without problems.. # uname -a Linux rg6830l 3.9.0-rc7 #1 SMP Mon Apr 15 09:40:44 BST 2013 x86_64 … Continue reading

Pi USB Saga – An Embarrassing Fail.. – and a Warning!

I had got tired of trying all the so-called ‘recommendations’ for fixing USB hub connectivity on the Raspberry Pi – including some from people who did not actually own one..   And yes, I do have the correct voltage power supply … Continue reading

VFAT is not LVM/RAID – and a Workaround…

Odd problem with kernel 3.6-rc3 on the Dreamplug… I had the usual /etc/fstab entry, with both the ext4 root and vfat boot devices configured, but now – despite LVM / RAID not being enabled in the kernel, the init/systemd process … Continue reading

The Pi / Hub / Power Saga – Running with Scissors..

Another option I just tried turned nasty very quickly…    I wondered what would happen if all external USB devices were connected via the (powered) hub, but the answer was soon apparent: usb 1-1.3.1.1: reset low speed USB device number 6 … Continue reading
