------- Additional Comments From [EMAIL PROTECTED] 2006-05-14 05:51 -------
it is due to this:
In acpi_ex_system_memory_space_handler:
...
case ACPI_READ:
*value = 0;
c0217846: c7 00 00 00 00 00 movl $0x0,(%eax)
c021784c: c7 40 04 00 00 00 00 movl $0x0,0x4(%eax)
After applying the patch below, it becomes:
In acpi_ex_system_memory_space_handler:
...
case ACPI_READ:
*value = 0;
c0217843: c6 00 00 movb $0x0,(%eax)
Because acpi_integer is U64.
Then, the kernel boot just fine, even if the first SSDT table_ptr ==dfe57c28,
and the
second SSDT table_ptr ==dfe57a28 , which was supposed to fail according to my
previous analysis.
Thanks,
Luming
