I'm having a problem with an AHA2940W with a AIC7870P chip on it.

It only probes 16 SCBs (is this normal?).  And periodically I get:

/kernel: ahc_scsi_cmd0: more than 256 DMA segs
/kernel: sd0: oops not queued
/kernel: biodone: buffer already done

I forced the driver (sys/i386/scsi/aic7xxx.c) to walk the SCBs 
and when I did this I get 255 SCBs.
