--- Comment #12 from Osbios <osbios@web.de> ---
Trying to copy 200 MiB, only the screen frezes. SSH works fine.
I can just kill -9 the program and everything is ok again. After that I have
this line in dmesg
[ 1851.802876] radeon 0000:01:00.0: failed to get a new IB (-512)
When I try to switch to console while my program still runs it appears to do
notihing, but after I kill -9 the program via ssh, I'm in the console.
I also tryed to move a windows around during the freeze, but that didn't work.
Sometimes the mouse pointer freezes, too.
Also the size of the buffer does not matter, relevant is how much bytes get
copyed by glCopyBufferSubData.
And the bigger the copy is the more likely the freeze seems to be.
With a 256 MiB copy I managed to get a kernel bug message in dmesg and could
not recover by killing the program.
Will bake me some fresh kernels now.
