Public bug reported:
Dear all,
First time send a report a bug, guide me if i provide not enough.Tq.
Okay,i have been debugging the error that i found in 8.04 ubuntu machine from
dmesg
[ 12.113000] ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not
found.
After goggling, it found that this error is harmless, but i still want to try
fix it.(Just not nice to have error in your kernel message, ;- ). i can fix it
by change parameter to initrid by disable the "acpi off" or i fix the dsdt.dsl
file.
So i choose second option. ("http://gentoo-
wiki.com/HOWTO_Fix_Common_ACPI_Problems" has guided me)
After i have disassambled the dsdt file, and i found two errors such as:
dsdt.dsl 203: Method (_WAK, 1, NotSerialized)
Warning 1079 - ^ Reserved method must return a value (_WAK)
dsdt.dsl 4844: Name (_PSW, 0x01)
Error 4077 - ^ Reserved name must be a control
method (with arguments)
For the first error i have solved by putting return value in that
method.
But, the second errors i couldn't find way to solve. i have googling out, but
still no suggestion.
Following is my spec:
