Pkg xen devel - Feb 2011 - Bug#614101: Debian 6.0 amd64 doesn't boot with Xen on Toshiba u300-13u

Package: xen-hypervisor-4.0-amd64
Version: 4.0.1-2

Either Xen, or the Dom0 kernel (I guess you know better) spits out
error messages about ata4 containing "status: { DRDY ERR }" (similar
error can be found googling DRDY ERR). 

I'm not putting the whole error message here because I couldn't
copy-paste the message at the booting stage.

I'm adding the autoconfigured menu entry just in case:

menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-xen-amd64 and XEN
4.0-amd64' --class debian --class gnu-linux --class gnu --class os
--class xen {
	insmod lvm
	insmod part_msdos 
	insmod part_msdos
	insmod part_msdos
	insmod ext2
	set root='(traveller-xen)'
	search --no-floppy --fs-uuid --set 68013fd3-04d9-4cbe-8d50-fc6b210fc088
	echo	'Loading Linux 2.6.32-5-xen-amd64 ...'
	multiboot	/boot/xen-4.0-amd64.gz placeholder  
	module	/boot/vmlinuz-2.6.32-5-xen-amd64 placeholder
root=/dev/mapper/traveller-xen ro  quiet
	echo	'Loading initial ramdisk ...'
	module	/boot/initrd.img-2.6.32-5-xen-amd64
}
