However, I have to backout sys/dev/acpica/acpi_cpu.c to 1.38 and sys/dev/acpica/acpi_pci_link.c to 1.14 such that it would not lockup at booting after sio0 probing. > > Symptoms: I don't use it very frequently, so I kldload if_ath as necessary. > Previously, it was load, config, and go, now... > > I see: > pci0: Failed to set ACPI power state D3 on (null): AE_BAD_PARAMETER > before the usual (and correct) ath0 status messages Did you try the latest source committed by njl@(about 3 hours ago)? I can't test it unless backing to home; however, they seemed to be able to eliminate the BAD_PARAMETER error under some circumstances: sys/dev/acpica/acpi_pci.c:1.18 sys/dev/acpica/acpi_powerres.c:1.23 > When I "up" the interface, I see: > ath0: hardware error; resetting > in a continuous parade scrolling up the screen I always put "if_ath_load=YES" in /boot/loader.conf. It works for me since the first time I purchased this card. Perhaps you would like to give it a try. > I tried setting hw.ath.debug, but the dump scrolls off faster than I can see > it.

The last resort: reboot with ACPI disabled. At least this saved me from troubles(if_em locks up) with recent -CURRENT.
