I have not tried the 32 bit variant. I am wondering if it is worth your time to boot a live CD after the lockup to occurs in order to mount your root and retrieve things like message log and Xorg.0.log.

Hello,

I'm trying to setup xen 4.0 with pvops kernel in ubuntu lucid 32 bit but I'm having some problems. The machine where I'm trying to do this is an eeepc 1000H, so debugging via serial port is not possible. The system boots normally if in single user mode and then I can go to multiuser mode but without X. As soon as X boots, the machine locks up without any error message visible on the screen. I've tried going single user -> multi user -> start X with a ssh connection started to try debugging remotely but the ssh connection gets dropped also.

The machine has an Atom processor, with 2GB of memory and an intel 945 GME graphics card.

My grub entry to boot Xen looks like this:
menuentry 'Ubuntu, with Linux 2.6.32.12 on Xen 4.0' {
        insmod ext2
        insmod ext4
        set root='(hd0,1)'
search --no-floppy --fs-uuid --set b260db59-8a4d-4f0a-8c21-df45b4dd0ad3 multiboot /boot/xen-4.0.gz dummy=dummy dom0_mem=1536M loglvl=all guest_loglvl=all module /boot/vmlinuz-2.6.32.12 dummy=dummy root=UUID=b260db59-8a4d-4f0a-8c21-df45b4dd0ad3 ro nopat nomodeset
        module /boot/initrd.img-2.6.32.12
}

I've already tried different combinations of nopat and nomodeset but to no avail...

Has anyone managed to get a X86 xen kernel booted under ubuntu lucid in xen 4.0? I've been trying this since the release of Xen 4.0 with pvops branch xen/stable-2.6.32.x without success...

Thanks in advance,
Luís Silva
