My monitor blanks out while loading xen kernel (fedora core 6).
 

i have installed fedora core 6 recently on my compaq
presario desktop. (p4 2.8Ghz 512MB) I had to disable the acpi while installing. I downloaded and installed xen-kernel through yum and grub.conf got modified appropriately.

title Fedora Core (2.6.20-1.3002.fc6xen)
root (hd0,4)
kernel /boot/xen.gz-2.6.20-1.3002.fc6
module /boot/vmlinuz-2.6.20-1.3002.fc6xen ro root=LABEL=/ acpi=off rhgb quiet


when i try to boot using the above title i get the following error message.

---
(XEN) system RAM 503MB
(XEN) heap 10MB
(XEN) PAE enabled:limit 16gb
(XEN) found SMP MP-table at 000f5fe0

(XEN) Using APIC drivers default
(XEN) ACPI:RSDP(V002 HP-CPC) @ 0x00f7f70
(XEN) unknown interrupt
the system stops to respond here.


I tried to modify the second line of the above title
to include acpi=off

title Fedora Core (2.6.20-1.3002.fc6xen)
root (hd0,4)
kernel /boot/xen.gz-2.6.20-1.3002.fc6 acpi=off
module /boot/vmlinuz-2.6.20-1.3002.fc6xen ro root=LABEL=/ acpi=off rhgb quiet


This time the monitor goes blank after displaying
[ok] when starting udev.

I am a linux newbie and i need to fix this problem to continue my project. plz help me! thanks in adv.

Make sure you have acpitool installed, then enable ACPI and try it again
