  Modified:    sys/i386/scsi  aic7xxx.c aic7xxx.h
  Log:
  Fix the abort code in the BUS DEVICE RESET case.  Needed to set cmdlen to 0.
  
  Ensure that queued commands are not touched by the abort code by setting
  the SCB status to indicate what queue it is in.
  
  Fix deadlocks when using SCB paging by using SCBs from the assigned_scbs
  queue or an SCB that completed during the same interrupt if needed.
  
  Don't ever use insl to pull SCBs from any of the controllers.  You can
  only do 8bit PIO reads.  This only affected SCB paging.
  
  With this checkin, SCB paging works quite a bit better, but I still have
  some problems with it that may be caused by a firmware problem in my
  PD1800s.  It seems that using a tag number higher than the maximum number
  of tags allowed by the device, confuses it.  For example, if I queue
  two commands, tagged 3 and 36, it never reconnects for tag 36.
