Ummm, strange...
Can you double-check that the config is the same, except for the new AoE stuff.

yes - the only difference is the AoE-root stuff.

diff .config .config_aeoroot

Quoted 7 lines

CONFIG_ATA_OVER_ETH_ROOT=y
CONFIG_ATA_OVER_ETH_ROOT_SHELF=1
CONFIG_ATA_OVER_ETH_ROOT_SLOT=1
Also, adding stderr=1 might give you some more output.

you mean adding this to the commandline?
mhh - doesn`t seem to make a difference.

if somewone might want to try if it behaves the same on their system, i put the working and the broken binary to

www.my-vserver.de/stuff/uml/linux.aoe_ok.bz2 www.my-vserver.de/stuff/uml/linux.aoeroot_notok.bz2

for taking a look into the relevant source, i tarred drivers/block/aoe, too :

www.my-vserver.de/stuff/uml/aoe.tar.bz2

TIA

BTW, is this x86_64 or i386? Yesterday, I rediscovered how to make this happen on x86_64. There's a timer loop in a driver that you get when you enable SERIO_I8042 that never finishes on x86_64, and it causes the hang right there.
