[Xen-users] Error starting domU (centos5) on xen3.2.0 : rtc: IRQ 8 is not free

["lestat thor" <lestathor@xxxxxxxxxxxxx>]

Hi.

I compiled the xen binaries and the kernel with the sources. 
DomO starts without any problems, but when I run domU, it stops and freeze.
My domU is a clone of my domO.

INIT: version 2.86 booting
rtc: IRQ 8 is not free.
modprobe: FATAL: Error inserting rtc 
(/lib/modules/2.6.18.8_HwiXen/kernel/drivers/char/rtc.ko): Input/output error
___________________________________________

I added this line at the end of the domU configuration file, and the machine 
starts, without freezing :
extra='xencons=tty'

But I still have the last error :
rtc: IRQ 8 is not free.
modprobe: FATAL: Error inserting rtc 
(/lib/modules/2.6.18.8_HwiXen/kernel/drivers/char/rtc.ko): Input/output error

Here is the result of 'hwclock' on my domO :
 -> lun 28 jan 2008 15:32:00 CET  -0.564342 secondes
And on my domU :
 -> nothing

Finally, my configuration file to compile the kernel :
