I've tried unstable tarball in the hope it will solve my problems with
non-working save / migrate on my machine, but using unstable branch,
domU ends in kernel panic just from start.
Because errors occure in every Xen version i've tested so far, i suspect
there is some hardware problem (maybe, but not probable, i had problems
with save/migrate on all machines), or some incompatibility with certain
gcc/glibc/whatever combination or maybe some obvious error in my
dom0/domU kernel configuration (the same config worked - without
save/migrate - on 2.0.3). Diff shows only slight changes between my
config and the default one - cpu type, some device drivers and
networking options.
Machine is built from common hardware - amd cpu, via kt600 chipset.
There are 5 PCI add-on cards and only one empty PCI slot. Maybe there is
IRQ routing problem?
If required, i can post additional data (output from ksymoops, both
kernel, System.map files etc.)
