ARM – Odroid U3 with Kernel 3.18-rc4 – Better, but still Slow…

Just installed the version of kernel 3.18-rc4 on the Odroid U3, and this time it completed the boot, but still had a ‘tombstone’:

The other annoyance (same as with -rc3) is that the CPU fan is running constantly…

As this is the mainline kernel version, some of the graphics drivers etc. are still work-in-progress..    I have tested with vnc, and that works OK with KDE, but performance is still very sluggish..
