I can remove 2GB of RAM, but I don't understand what you want to see. I have
made some tests _without_ X (X is not running anymore, even on an other
virtual
console). Thus, I only have on my test system a text based linux system.
If this bug can be observed without X, I don't understand how this bug can be
X
related.

Test program is a huge multitasked/multithreaded code that does some SQL
queries. I don't know if crash comes from huge cpu usage or disk usage (or
some
other components like raid subsystem), but it seems to be kernel related, not
X
related as I knew. I have to restart several times my test program to see a
crash and I cannot debug because sysrq magic key doesn't work anymore.

Bertrand, we've seen issues where reducing the size of RAM miraculously fixed
issues with X. The theory was that there is an overlap between the PCIe BAR
address ranges and the main memory.
Since text mode also uses a framebuffer (and thus VRAM which is mapped
somewhere)
I could envision such problems there even. It was just a wild guess.
If reducing the size of RAM helped it would indicate that the problem was
related to the other issues we've been seeing.
However since you are seeing this issue even without X it doesn't seem to be
related to the RadeonHD driver at all.
I will therefore close it with NOTOURBUG for now.
If you need further information please feel free to continue the discussion on
this ticket.
