Thanks to juston_li on the NVIDIA Devtalk forum, there is specific detail of the changes needed for Kernel 4.7 compatibility.. Details are at https://devtalk.nvidia.com/default/topic/938665/linux/linux-4-7-rc1-367-18-build-errors/ The first issue is interesting, as it is due to a Kernel Dev. deciding to introduce a new variable – radix_tree_empty – in Kernel 4.7-rc1, that happens to have the same name as … Continue reading →
Thanks to g, from their comment on my previous article ( https://rglinuxtech.com/?p=1746 ), there may be a more correct vmnet fix than simply ‘commenting out the code’.. Replace dev->trans_start = jiffies with netif_trans_update(dev) in netif.c I have made this change, and VMware 12.1.1 is – so far – loading and running OK, as usual.. Robert Gadsdon. May 30, … Continue reading →
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 https://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 →
