Subject: acpi=off vs. blacklist
Date: Tue, 31 Jul 2007 12:35:53 +0200 [thread overview]
Message-ID: <200707311235.53302.philipp.marek@bmlv.gv.at> (raw)
Hello everybody!
I have two machines which freeze during boot; this seems to be ACPI-related,
because with acpi=off they start.
The first one is the HP DC 7700; some summary can be seen on
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1081719
It hangs after a line
ACPI assume root bridge[\sp_.pci0] bus is 0
The second one is a notebook; a Roda Rocky III+ RK886EX, which just shows a
blank screen.
As we drive many machines from the same kernel image via PXE, I tried to
insert them into drivers/acpi/blacklist.c; but that doesn't help, either -
the notebook hangs as before, no matter whether I set is_critical_error or
not.
[ I suppose I wrote the entries wrong; is there some HOWTO? I used
acpidump/acpixtract/acpitbl, copied other blacklist entries, and took
"OEM Table ID", "OEMID", "OEM REVISION". Help? ]
Using the "ACPI debug" kernel option showed no more messages.
Help, please? What can/should I do now?
Regards,
Phil
