I have the same (or similar) symptom on an old core-duo Toshiba. It
seems to occur just before hwpmc would normally show in the log:

kernel: ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
kernel: ada0: <Hitachi HTS725050A9A364 PC4OC70E> ATA-8 SATA 2.x device
kernel: ada0: Serial Number 101105PCK404VLKU1WXJ
kernel: ada0: 150.000MB/s transfers (SATA 1.x, UDMA6, PIO 8192bytes)
kernel: uhub2: 2 ports with 2 removable, self powered
kernel: uhub3: 2 ports with 2 removable, self powered
kernel: ada0: Command Queueing enabled
kernel: ada0: 476940MB (976773168 512 byte sectors: 16H 63S/T 16383C)
kernel: ada0: Previously was known as ad4
kernel: SMP: AP CPU #1 Launched!

 ** non working kernel panics here **

kernel: hwpmc: SOFT/16/64/0x67<INT,USR,SYS,REA,WRI> TSC/1/64/0x20<REA>
IAP/2/40/0x3ff<INT,USR,SYS,EDG,THR,REA,WRI,INV,QUA,PRC>
kernel: Timecounter "TSC" frequency 1662542340 Hz quality 1000
kernel: Root mount waiting for: usbus4

On another machine, which has 4 drives in two geom mirrors, it refuses
to find ada0 or ada1. It reports a CAM timeout on the ATA-IDENTIFY phase
with an apparently non-functioning interrupt problem. Reverting to a
kernel built on July 27th restores normal behaviour,
