Bug in all modern 4.x kernels with TORAM (live linux)
 
Hello,

There is an important bug in all 4.x kernels. They are released with the default options that do not allow the TORAM to work properly.

Tweaking during compiling the kernel is especially needed.

This report is made on Ubuntu and Debian running distros.

I compiled the following kernels on Debian.
Code:

3.16.1
3.19.1
3.19.8
4.5.5
4.6.1

Kernel from the classical source: https://www.kernel.org/pub/linux/kernel/

Sometimes it works when I heavily change the .config during the kernel compiling. I have to find out which parameter (.config) allows to make TORAM works and even at each boot.

I have tried with grub1.98, grub 2 and syslinux.

TORAM is in my opinion pretty unstable.

More reading on Ubuntu similar issue: http://askubuntu.com/questions/44881...up-kernel-pani

I hope that there will be soon interests, help and a fix on new 4.x kernels.

Further work: I will try on my slackware machines, but I highly suspect that it be a similar result.

Looking forward for help.

Best regards and happy new year

I don't know what "TORAM" is but I am running 4.8.16 and how would I check the .config for the data you are looking for?

"TORAM" ("to RAM ...") is a feature that is intended to let Linux run completely from RAM. It seems to have problems.
