On bootup of 2.6.29-rc2 a kernel panic in acpi_ns_get_parent_node occurs.
This is the backtrace (written down from the screen, maybe incomplete):
acpi_ev_execute_reg_methods
acpi_install_address_space_handler
acpi_ec_space_handler
acpi_init
ec_install_handlers
acpi_ec_ecdt_probe
acpi_init
fbmem_init
_stext
register_irq_proc
proc_pident_readdir
kernel_init
child_rip
kernel_init
child_rip
RIP [...] acpi_ns_get_parent_node
I can provide a screenshot (270kB) if this information is insufficient.
The system booted with 2.6.29-rc1 so a recent change must be the cause
of this panic.
The system is an Asus B50A laptop running an x86_64 kernel.
Maybe this problem is related to these messages I was seeing in bootups
of previous kernels:
[ 0.176398] ACPI Error (nsaccess-0434): ACPI path has too many parent
prefixes (^) - reached beyond root node [20080926]
