ok, building without CONFIG_4KSTACKS fixed that panic, but I have other 
problem - is it possible to share one serial port between grub, xen itself 
and dom0?

It panics also if I use

kernel (hd0,0)/xen.gz dom0_mem=32768
module (hd0,0)/vmlinuz-2.6.9-xen0 root=/dev/hda3 ro console=ttyS0,115200

my grub.conf contains

serial --unit=0 --speed=115200
terminal serial console

the (stripped) message is:

devfs: 2004-01-31 Richard Gooch (rgooch@xxxxxxxxxxxxx)
