Hi all,

I've seen a similar FUBAR with the DSDT on resuming (but not on the
initial boot) with 2.6.11.

It might (!?) be related modules not having suspend/resume support, such
as the to the firewire (1394) modules. (I also saw this problem causing
the touchpad to get associated with the keyboard drivers so moving the
mouse created a character stream. Much fun!)

A little more information is on the Kernel bugzilla:

        http://bugme.osdl.org/show_bug.cgi?id=4340

As a workaround, i have found that blacklisting the ohci1394 module for
hotplug solves the problem... [1]

        echo ohci1394 >> /etc/hotplug/blacklist.d/ieee1394-suspend

I can now suspend without any problems. (And since I don't have any 1394
devices, that doesn't worry me).

If this works for you, it might be worth posting a "me too" comment on
the above bug including your laptop's specifications, the error messages
that you see and how you worked around it.

cheers,
Stuart


[1] Actually, I have ieee1394 and eth1394 also blacklisted in here as
well.
