I had a (rare) problem with power to my computers recently. The battery in my UPS had died (causing really annoying beeping warnings..) and the power also went out briefly, causing all systems to suffer a genuine power fail condition. The Linux systems all came back (after some extra – brief – systemd-fsck operations) in – literally … Continue reading →
Bacula is great for Linux – to – LTO tape backups, but the YUM updates can – at least on my system – sometimes leave it in an unusable state.. For some reason, the update tends to leave the libraries in /usr/lib64 in a mess, with some pointing to postgresql instead of mysql, and some still in … Continue reading →

Ran 3.5-rc2 for while.. Seemed stable at first, but now getting USB3 XHCI errors: xhci_hcd 0000:04:00.0: ERROR Transfer event TRB DMA ptr not part of current TD usb 10-1.1: reset SuperSpeed USB device number 3 using xhci_hcd usb 10-1.1: Parent hub missing LPM exit latency info.

Found that the ‘latest’ (11.2.x) Adobe Flash Plugin for Linux (x86_64) makes YouTube videos look like something from a bad trip.. Tried different browsers, but the fault was still there.. Videos from news sites (BBC etc.) seemed to be OK.. So – reverted to 11.1 version of Flash Plugin (from Adobe archives) and all is well, again.. … Continue reading →
Linux kernel version 3.4.1 was not out yet, but there is a 3.5-rc1 already.. Compiled and installed, and the existing (patched) VMWare 8.0.3 installs and runs OK, and the latest NVIDIA driver (295.53) installs cleanly.. $ uname -a Linux rglinux 3.5.0-rc1 #1 SMP Mon Jun 4 13:33:33 BST 2012 x86_64 x86_64 x86_64 GNU/Linux Now – to see … Continue reading →
Kernel 3.4.0 just released… Not on kernel.org yet, so downloaded from github (https://github.com/torvalds/linux). The latest version of the NVIDIA linux drivers (295.53) already supports kernel 3.4x, and the latest ‘weltall‘ patch for VMware (8.0.3) also supports this kernel version, so should be good to go.. Now – to see what’s new/improved/fixed/broken! Update: compiled/installed, and everything seems to … Continue reading →
After all the Pi excitement, back to (relative) normality.. I upgraded my main (x86_64) systems to Fedora 17, using YUM, as usual.. I have found that using the DVD is messy, and sometimes leaves the system in a ‘hybrid’ state, and then the DVD versions of many packages need to be updated, in any case! Compared to … Continue reading →
Despite previous ‘tweaks’, I have been experiencing continuing problems with SD Card Linux performance, and with the unreliable operations of yum / rpm, with associated db corruption, when they have to be ‘killed’ after hanging.. Based on two excellent pieces of prior research: http://blogofterje.wordpress.com/2012/01/14/optimizing-fs-on-sd-card/ and http://www.raspberrypi.org/forum/projects-and-collaboration-general/optimizing-linux-for-flash-memory – I will be having a stimulating (!) time performing formatting … Continue reading →
