The guest stack is now always printed when dom0 fails, which is why
you get a more relevant error message.
Could you please add "earlyprintk=serial" to the linux command line
options (CONFIG_EARLY_PRINTK should be enabled in your kernel config
file by default -- if not, please enable it) and add a call do
dump_stack() at the beginning of acpi_table_compute_checksum in
linux-2.6.11-xen-sparse/drivers/acpi/tables.c. Thanks!
