[Xen-ia64-devel] compilation xen unstable on a ia64 debian - working !

[Peter Van Biesen <peter.vanbiesen@xxxxxxx>]

Hi everyone,

I compiled the xen-unstable.hg. This went ok, I changed my elilo.conf and 
rebooted. Booting went ok but I did not get a login prompt. I always get :

init: Id "T1" respawning too fast: disabled for 5 minutes

Apparently the console line in the debian kernel gets mapped to /dev/ttyS1 
while in the xen kernel it is mapped to /dev/ttyS0 . Strange behaviour but 
fortunately my sshd was running so it was quickly fixed. 

I'll see if I get a domU running.

Thanks for the help !

Peter.
