Can you suggest what a good place 'earlier in the failure
path' might be?
I expect you'll get an error message from Xen before the BUG in domain
crash. See where the error message comes from, and then add the
show_guest_stack to the appropriate path.
A debug build gave the following crash.
It's different, a page fault, but there's no previous error message
that lets me see where to put the show_guest_stack.
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!
OK, I did that and planted a few dump_stack() calls in the acpi code:
