Fedora 33 will be using ZRAM as standard for swap, rather than a partition or swapfile on disk. I had no problem with this on a new F33 install (Odroid H2Plus) but after upgrading an existing Fedora 32 system it refused to initialise, and ‘/dev/zram0‘ did not exist. Research revealed that the documentation for much of this … Continue reading →
I have been testing Fedora 33 pre-release, and on x86_64 it seems relatively stable (usual caveats…) but on arm64 systems (Odroid N2 and Pi4) I found that after compiling a new kernel (5.8.3), the system booted, but login was impossible, and screen output was missing (uart/console was OK). Kernels compiled with Fedora 32 all booted OK, and … Continue reading →
The Intel SOC AP42 system is not supported by Grub2-EFI, but boots using rEFInd (see article at http://rglinuxtech.com/?p=2021 ). I had hoped to prevent the ‘automatic’ (re)install of grub2-efi etc by masking the (minimal) grub installation of grubby etc. – necessary to support the Kernel # make install function – using # rpm -e –justdb –nodeps <package>. … Continue reading →
Tried Kernel 4.16.7 on Fedora 28 (GCC 8.0.1), and this now compiles successfully, although still with a lot of ‘warnings’.. I use grub-customizer with each new kernel, and the F28 version of this fails: # grub-customizer Error creating proxy: The connection is closed (g-io-error-quark, 18) *** initializing (w/o specified bootloader type)… * reading partition info… /usr/include/c++/8/bits/basic_string.h:1048: std::__cxx11::basic_string<_CharT, … Continue reading →
I am setting up an HP Z820 as – primarily – a video creating/editing/restoring system, but I need to be able to boot into Windows 7 Pro (for Vegas Pro, AviSynth, Prodrenalin, Mercalli, etc. etc..) and Linux (Fedora).. I had set up dual-boot systems before, and I am still using Windows 7 Pro SP1, but this time … Continue reading →

After upgrading four Fedora systems (x86_64) from release 26 to 27, using # dnf system-upgrade download –refresh –releasever=27 –allowerasing –nogpgcheck –best -y, two of these worked OK, but two failed – with a sudden reboot, back to F26 – and no (apparent) error displayed, after # dnf system-upgrade reboot had rebooted the system, and the upgrade process … Continue reading →
The original ‘SeaBios’ BIOS on my Acer c720p was a little clunky, so I decided to make the plunge and update it to a ‘proper’ Linux-friendly BIOS.. There is a known/good one available, but it is UEFI-only, so will involve changing the filesystem/partition layout on an existing system.. Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors … Continue reading →
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 →
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 ). Robert Gadsdon. January … Continue reading →
