Hello!
I'm trying to boot a 32bit DomU Kernel on Xen 3.2 with a 64bit Dom0.
The Kernel is booting, but I get an error with the virtual disks.
I have tried 2.6.24 and 2.6.25-rc3. Both the same problem.
PAE is enabled.
My Xen-Config:
kernel = '/boot/xen/vmlinuz-2.6.24-1-xen-686'
ramdisk = '/boot/xen/initrd.img-2.6.24-1-xen-686'
memory = '256'
extra="console=hvc0"
root = '/dev/xvda1 ro'
name = 'test'
dhcp = 'dhcp'
vif = [ '' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
disk = [
'phy:data/test-disk,xvda1,w',
'phy:data/test-swap,xvda2,w'
]
#disk = [
# 'phy:data/test-disk,0x20201,w',
# 'phy:data/test-swap,0x20202,w'
# ]

Kernel panic - not syncing: Fatal exception in interrupt
Sometimes the I/O error is on xvda1, and sometimes on xvda2.
Thanks
