Thanks to Justin Palermo, there is a patch for VMware 12 vmmon and vmnet problems he identified with the later Kernel 4.6-rcs. See comments on my earlier 4.6-rc1 article for details: http://rglinuxtech.com/?p=1679 I have applied the patch to VMware 12.1.0, on Kernel 4.6-rc4, and VMware now compiles and runs OK.. Robert Gadsdon. April 22, 2016. … Continue reading →
I had been running Kernel 4.6-rc2 on the Radxa Rock2 without any issues, and decided to update to recently-released Kernel 4.6-rc4.. Brief details of changes from -rc3 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.2/00610.html The boot failed, and I then compiled/installed 4.6-rc3 to see if that would have been OK, and it was.. I then noticed something odd in the failed … Continue reading →
After a lot of searching – and more testing (mostly unsuccessful..) I finally have a set of two patches that fix the Ethernet driver problem with the Rock2 in 4.6-rc1.. The problem is that the stmmac driver is common to several SOC setups, and each maintainer seems to have produced their own version of a fix.. The … Continue reading →
Updated the Rock2 to Kernel 4.6-rc1: ……… Fedora 23 (Twenty Three) Kernel 4.6.0-rc1 on an armv7l (ttyS2) ……………….. # uname -a Linux rgrock2 4.6.0-rc1 #1 SMP Sun Mar 27 03:47:06 EDT 2016 armv7l armv7l armv7l GNU/Linux The stmmac Ethernet driver bug from 4.5 Final has still not been fixed, and the driver code has changed in 4.6-rc1, … Continue reading →
Finally managed to cobble together a rudimentary case and fan with heatsink for the rock2, and now I can compile correctly (# make -j5, etc..) and run # git clone… without the system overheating and rebooting.. Just two sheets of perspex, and some assorted m3 nylon pillars and screws.. The 5V power supply needs to be around … 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 →
After a lot of testing, and some more confusion, I have managed to get the Rock2 to boot using the latest (2016.03-rc3) version of U-Boot, and the latest kernel (4.5-rc7) As previously, there was a lot of conflicting information……. I started by booting into the semi-proprietary 3.10-based kernel on the SDcard, and then erasing the eMMC (dd … Continue reading →
Just acquired a 64-bit Odroid C2: As usual, I installed Fedora 23 aarch64 on it: Fedora 23 (Twenty Three) Kernel 3.14.29 on an aarch64 (ttyS0) ………………… # uname -a Linux rgc2 3.14.29 #1 SMP PREEMPT Wed Mar 9 11:14:41 PST 2016 aarch64 aarch64 aarch64 GNU/Linux The only kernel source available – so far – is a heavily-patched … 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 →
I did a clean install of Fedora 23 on my new ‘built from recycled components‘ crash-and-burn test system recently, and all went reasonably well – apart from – apparently – having to re-partition an already-partitioned drive (!)… After booting for the first time, I found that a ‘bridged’ network link – virtbr0 – was active.. As I … Continue reading →
