Hello,
I've bought a new Laptop, HP EliteBook 8530w. I tried to install
Ubuntu on it and noticed that ACPI doesnt work (I made a Ubuntu bug
report here
https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/288385). The
Laptop hangs on bootup. With the kernel parameter acpi=ht, which
basically disables acpi except the smp feature, the kernel boots.
Becauce it is very anoying to work with a laptop without acpi I
decided to try to fix it myself. I dumped the acpi table (sudo
acpidump -t DSDT -o dsdt.dat -b) and tried to disassemble/compile it
with iasl (iasl -d dsdt.dat/iasl -sa dsdt.dsl).
The errors I get are maaany of the "Object does not exist":
dsdt.dsl 49: Store (\_SB.PCI0.RP03.PDSX, IECP)
Error 4062 - Object does not exist ^ (\_SB.PCI0.RP03.PDSX)
dsdt.dsl 50: Store (\_SB.PCI0.RP05.PDSX, DECP)
Error 4062 - Object does not exist ^ (\_SB.PCI0.RP05.PDSX)
Then I have this Errors:
dsdt.dsl 611: VBRE (0x87, If (LEqual (Local0, 0x02))
Error 4094 - ^ syntax error,
unexpected PARSEOP_IF, expecting ',' or ')'
dsdt.dsl 611: VBRE (0x87, If (LEqual (Local0, 0x02))
Error 4094 - syntax error, unexpected ')' ^
dsdt.dsl 611: VBRE (0x87, If (LEqual (Local0, 0x02))
Warning 1104 - Result is not used, operator has no effect ^
dsdt.dsl 614: })
Error 4094 - ^ syntax error, unexpected ')'
And this one:
dsdt.dsl 720: Scope Name (_HID, EisaId ("PNP0C0B"))
Error 4094 - ^ syntax error, unexpected PARSEOP_SCOPE,
expecting $end
My questions: First, can it be that the kernel can boot with acpi with
a fixed DSDT table loaded? Can somebody help me fixing the table
(especially Object does not exist, does I have to define all this
things with External?) ? When I try to fix them and I do it wrong, can
I break hardware with it?
I thought when I've fixed the table, im going to open a bug report and
then this can be fixed in acpi, is this the right approach?
The full log can be found here: http://paste.ubuntu.com/63256/
The disassembled DSDT can be found here: http://paste.ubuntu.com/63257/
Any help would be greatly appriciated,
Stefan
