Kernel 4.6-rc5 is out, and brief details of changes from -rc4 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.3/00178.html Kernel 4.6 seems to have a habit of continuing later-rc breakages with VMware and NVIDIA, compared to previous kernel releases.. The VMware 12 fix for 4.6-rc4 (see http://rglinuxtech.com/?p=1706 ) still works OK with 4.6-rc5, but even the latest NVIDIA driver – 364.19 breaks … Continue reading →
Kernel 4.5-rc7 had booted successfully on the Radxa Rock2, but 4.5 Final failed, as the SDcard was ‘loaded’ just too late: mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) dwmmc_rockchip ff0f0000.dwmmc: 1 slots initialized ……………………… VFS: Cannot open root device “mmcblk1p1” or unknown-block(0,0): error -6 ………………………… Kernel panic – … Continue reading →
I recently acquired a vintage (2006?) Minolta Elite 5400 II scanner, and – according to the VueScan support info, I needed to ”set up libusb device protections”.. That info included a link to a somewhat ancient SANE USB support page – last changed in 2003!.. That rang a bell, and I guessed that I had to mess … Continue reading →
Updated to the latest Plasma Desktop, on one of my systems (Fedora 23, x86_64), and found that the ‘Favorites’ had all vanished, apart for xterm.. My other x86_64 system updated OK, with all the ‘Favorites’ intact.. Rather than hunt down all the apps and ‘add to favorites’ for each one, I found the old Favorites again, as … Continue reading →
I updated the CuBox-i4-Pro (Fedora 22) to Kernel 4.1-rc2, but the (re)boot process was very sluggish, with several key commands failing: ….. systemd[1]: Unit dbus.service entered failed state ….. [FAILED] Failed to start Login Service. ….. [FAILED] Failed to start Modem Manager. ….. [FAILED] Failed to start Avahi mDNS/DNS-SD Stack. ….. [FAILED] Failed to start Network Manager. … Continue reading →
I finally got my old DreamPlug working again, but found that the power would fail intermittently.. After checking for software faults, I tracked the problem down to the power supply cable ‘clip-on’ connector.. The problem was caused by the internal connection between the two external pins and the internal slide-on metal tabs being loose, and causing … Continue reading →
The CuBox-i4 Pro booted Kernel 4.0-rc1 OK, but – although eth0 was present – there was no network connection possible.. I found a similar problem described on the Linux Arm Kernel mailing list: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/325249.html According to the info there, I changed linux/arch/arm/mach-imx/mach-imx6q.c as follows: Around line 214, change clksel = ptp_clk == enet_ref ? IMX6Q_GPR1_ENET_CLK_SEL_ANATOP : IMX6Q_GPR1_ENET_CLK_SEL_PAD; … Continue reading →
I have hacked together a kernel-version-friendly fix for the latest NVIDIA driver (346.35) which works with Kernel 4.0-rc1 (and later) and also for previous kernel versions.. Thanks are due to juston_li for producing the actual code changes needed.. https://devtalk.nvidia.com/default/topic/813458/linux/linux-4-0-rc1-346-35-build-error-_cr4-functions-fix/ Unpack the NVIDIA driver: ./NVIDIA-Linux-x86_64-346.35.run -x Edit NVIDIA-Linux-x86_64-346.35/kernel/nv-pat.c Around line 34, change { unsigned long cr0 = read_cr0(); … Continue reading →
I had occasion to install an ancient GTK+ app, recently, and had to use # rpmbuild –rebuild xxxxx.src.rpm to (re)create some old RPMs from source.. I got the following error: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c: In function ‘php_gtk_args_from_hash’: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c:410:4: error: format not a string literal and no format arguments [-Werror=format-security] php_error(E_WARNING, buf); ^ So, I needed to remove the –Werror=format-security parameter … Continue reading →
VMware have released VMware Workstation version 10.0.4, but it still doesn’t compile with Kernel 3.17 or later.. In fact, the only ‘fix’ appears to be for ‘memory problems with Windows 8.1 and Server 2012’, according to the release notes: https://www.vmware.com/support/ws10/doc/workstation-1004-release-notes.html It would appear that up-to-date compatibility is being kept for the next major release, which is due … Continue reading →
