Since back before FreeBSD 5.0 I have had a problem where my audio lost sync after a suspend/resume when ACPI was used on my ThinkPad T30. (No problems with APM, last I tried it.) As a result, I have not used suspend on my laptop very much. Every now and then, when I see commits that appear relevant, I try again, and one minute of audio will play in 50 seconds, not sounding too good while it is at it. Well, as of about 2 weeks ago, it works! I can now suspend and resume and everything seems to work. I can't say for sure, but I think imp's recent power state work is responsible. I know it worked VERY briefly when he did his first commit of power state code long ago, but after fixing lots of problems the original code caused, it never worked again. As of today I can suspend in either text or X11 and resume works. The only MINOR issue is that the video does not come back on when I resume in X11. I just switch to a vty until the back-light comes on and then go back to X. I still see rather high power consumption while suspended and I intend to play with power states to see if I can improve the situation. I also need to get radeontool. In any case, thanks to imp, Nate, Bruno, and all the folks who have made a mammoth contribution of time to make ACPI work well on FreeBSD. -- R.
