Thinkpad t43p suspend/resume only once

[Richard Kolkovich]

Hi,

On my T43p, I can suspend to RAM (S3) and resume once.  After this, nothing
happens when I close the lid (until a reboot).  I started digging into this
today, and it looks like the acpi device is in a bad state after the resume.
Running devd -dD from a terminal shows no output from ACPI buttons after the
resume.

I discovered today, however, that I can run acpiconf -s S3 to regain my ability
to sleep/resume.  This will suspend the machine and immediately resume it, after
which devd shows output again.

I'm running RELENG_7 as of about March 25th.  I've only run 7.0 on this laptop,
so I've always had this problem.  I've just now gotten a chance to work on
finding a fix.

Please CC me, as I'm not subscribed to freebsd-acpi.  Thanks,
