What do u mean in "mixed 64b xen/32b dom0 stack"? is the 2.6.30 kernel
a 32b kernel?
Here is the result of 'uname -a':
Linux dell-e6400 2.6.30-rc3-tip #1 SMP Mon Jul 6 13:43:07 EDT 2009
x86_64 GNU/Linux
What does it mean, that vbetool doesn't use the right emulation library?
Regarding the XCI tree - are there specific patches for the 'vbetool'
and other stuff? will i be able to find them in the XCI kernel
patch-queue?
BTW - will compiling a 64b 2.6.30 kernel solve such issues?
