Do you recall which acpi enabled kernel works for you?
If never, I guess your system don't support ACPI .
If yes, this should be resolved. Please enter a acpi bug into
bugzilla.kernel.org with sufficient info : dmesg,lspci -vvx,
/proc/ioports, acpidump output... w/ acpi=off.

Hi,
The kernel version mentioned in the subject won't boot because the ACPI
system does not get initialized; the system freezes on an outb() in
acpi_os_write_port() i.e. it does not do anything anymore and just hangs.
Here is the `stack trace' I managed to extract via debugging output:
-- acpi_os_write_port(0xb2, 240, 8)
-- acpi_hw_set_mode(ACPI_SYS_MODE_ACPI)
-- acpi_enable()
-- acpi_enable_subsystem(~ACPI_NO_ACPI_ENABLE)
-- acpi_early_init()
...
Notes:
* acpi_os_write_port(): I printk'd the arguments; the port
formatted with %#x and the value with %u.
* acpi_enable_subsystem(): I removed ACPI_NO_HARDWARE_INIT
from the arguments because it is not used anymore.
In this context I want to mention that it probably can be
removed from include/acpi/actypes.h generally.
Random question:
I noticed that acpi_gbl_FADT is declared in
include/acpi/acglobal.h but where is it actually defined and
initialized?
HTH,
Hannes
