I have seen a couple of issues in ACPI. One is a regression (and it's the most significant.) I have been using John Baldwin's DPMS patch to /sys/dev/acpica/acpi_video.c to turn off the display when I suspend(S3). This has been working fine since I first installed the patch about a month ago. When I did zzz(8), the display would switch back to ttyv0, turn off and the system would fully suspend. Now, it does not turn off the display. The system mostly suspends, but the back light remains on and the video is not blanked. This is exactly the way it was behaving prior to the patch. Another issue involves the battery. The value of the battery status returned is unique to each battery and the value returned to queries (likely APM) by either the gnome-battery applet or the apm(8) command is the worst of the two. This means when running with two batteries, as soon as the first starts to discharge, I see "Low" reported even though the primary battery is a 100% charge. I believe the lowest value should be reported, not the highest. (I mean in terms of what ACPI returns, not battery charge.) I thought that it had worked this way at one time. Finally, if I add a battery after the system is up and running, ACPI no longer returns meaningful values and never "sees" the new battery. (I don't know if this is in the FreeBSD code or BIOS, so I dont' know if it can be fixed.) I see that there have been a few updates since I last updated the kernel, but I need the system on-line right now, so I can't update until tomorrow. This applies to my IBM T30. System current as of June 26. I can post my acpidump and other stuff if needed. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
