The addresses are back to pre-Mar 31, but ath still doesn't attach, verbose dmesg here: http://people.freebsd.org/~deischen/ath/dmesg.fails.no_new_pcib.txt The relevent ath messages are below. -- DE pcib2: requested memory range 0x88000000-0xffffffff: good unknown: Lazy allocation of 0x10000 bytes rid 0x10 type 3 at 0x88000000 cbb0: Opening memory: cbb0: Normal: 0x88000000-0x8800ffff cbb0: Opening memory: cbb0: Opening memory: cbb0: Normal: 0x88000000-0x8800ffff cbb0: Opening memory: found-> vendor=0x168c, dev=0x0013, revid=0x01 domain=0, bus=3, slot=0, func=0 class=02-00-00, hdrtype=0x00, mfdev=0 cmdreg=0x0002, statreg=0x0290, cachelnsz=0 (dwords) lattimer=0x00 (0 ns), mingnt=0x0a (2500 ns), maxlat=0x1c (7000 ns) intpin=a, irq=11 powerspec 2 supports D0 D3 current D0 ath0: <Atheros 5212> mem 0x88000000-0x8800ffff irq 11 at device 0.0 on cardbus0 cbb0: Opening memory: cbb0: Normal: 0x88000000-0x8800ffff ar5212SetPowerModeAwake: Failed to wakeup in 40ms ar5212SetPowerModeAwake: Failed to wakeup in 40ms ath0: unable to attach hardware; HAL status 3 cbb0: Opening memory: device_attach: ath0 attach returned 6
