Hi CB5-311 users,
now with Mesa 18.1 and Tegra support in the official repos we really just need a working current kernel to finally have a great Linux notebook computer.
I experimented a little more, and tried the rc1 of Linux 4.18. I did a "make tegra_defconfig", as described earlier in this thread. Trying to boot lead me to the familiar black screen... but after resetting, and going booting back to the working Linux 4.15, I could verify that booting Linux 4.18(rc1) had actually been successful:
$this->bbcode_second_pass_code('', 'journalctl -b-1')
I'll attach the output both of this, and of /var/log/Xorg.0.log.old. Maybe someone else can figure out what's going wrong? Or who should I ask? The #tegra channel?
Now I also have a USB network adapter, and I can ssh into the system when running the 4.18 kernel.
Slightly off topic: as a fan of ARM computers I also have a cubox-i, which happens to also have 4 GByte of ram. This machine does not support LPAE, though. The 4 GByte can still be used, but only when initialized correctly with the right version of u-boot. I don't understand the details of this, and I'm not interested as long as it's working... I was just thinking this might somehow be useful information for creating a kernel that works on non-lpae systems, and still lets our systems use their full 4 GByte.
