Re: the hang regression...
Without the patchset from comment #56 that reverts Linux
to ACPI 1.0 suspend order...
If USB is unloaded before suspend is invoked, then suspend works, yes?
So it is possible that the Linux/Windows incompatibility here
isn't the _PTS vs. D3 suspend order, it may be that Linux
is suspending USB differently than Windows.
Please provide the output from cat /proc/acpi/wakeup
As the strings in this file are arbitrary, please echo
each device name into the file to get as many of the
devices enabled for wakeup as you can. Then see
if that change makes the hang go away.
The other thing I wonder about is the mechanism for
the actual hang. It seems to occur when we are
writing a number reflecting the OS version to an
IO address. It is likely that this write actually
triggers and SMI and the root failure here is that
the SMM code in the BIOS crashed. Please see if
you can have any effect on the hang by changing
what number is written here. While you could
edit the DSDT, it would be better to use bootparams:
The ABIT and ASUS have the same AML code for asking
what OS is running.
You can make them think they are running Windows 2000 this way:
acpi_osi="!Windows 2001"
You can make it think they are running Windows NT this way:
acpi_osi=
