Summary: 5.1-RELEASE on ThinkPad 570 (2644-BAJ) freeze at suspending
Product: Base System Reporter: Toshiboumi Ohta <bugbird>
Component: kernAssignee: freebsd-bugs (Nobody) <bugs>

Description Toshiboumi Ohta 2003-08-13 05:10:18 UTC 
As, ThinkPad 570's BIOS does not support ACPI functions,
I configured apm(4) and OLDCARD environment on my note,
and disabling ACPI module by "device.hints".

It seems working good, when suspending from charactor 
console environments, but X11.

The complete hang occur with remaining graphical
displaying.  And no way to recover except power
resetting.

Interest thing is that, when switching to charactor
console by virtual console function (a.k.a. Ctl-Alt-F?? ),
the hibernation work with no problems.

I also compared with 4.8-RELEASE, but it work with no
problems.

How-To-Repeat: 
configure "device apm" on kernel configuration file
disable ACPI / enable APM functions by "device.hints"
append 'apm_enable="YES"' entry on "rc.conf"
startup X11 GUI
pushdown Fn-F12 (specify hibernation) or type "zzz"
on command line.

Try to put the following into your kernel config:

options SC_NO_SUSPEND_VTYSWITCH

This helped on my T20, which had the same problem.

So I guess this PR can be closed?
