PROBLEM:  (QAR 68463, QAR 65310)    (Patch ID: OSF435-149)
********
This patch allows the customer to connect LVD devices to the internal
connectors of an adapter that uses the itpsa driver. It also enables full
LVD functionality in the driver.

If an attempt is made to connect drives to the internal connector without
this patch then they will not be seen by the operating system. This patch
also enhances the performance of the itpsa adapter.

PROBLEM:  (QAR 7147)    (Patch ID: OSF435-204)
********

This patch fixes the following problems:

1.) A deadlock condition when both SCSI channels are running.
    A check before issuing a soft reset to the chip is now
    executed to prevent this problem. 

2.) Corrects a data corruption error on wide devices when an 
    odd size transfer is done such that the device disconnects 
    at just the right time.  When this occurs, it is possible 
    to loose the last byte of a write from a scatter gather 
    entry (the I/O continues with the next S/G entry and skips 
    the last byte of the previous entry).  This problem has been
    seen specifically on RZ2EA-LA and RZ2CA-LA (Quantum Atl
    as III) drives with a write of 25089 bytes starting at 
    sector 77263.

3.) Problems with I/Os over 4Mb.

********

This patch fixes the following problems:

1) Problem with the ITPSA driver for KZPCM and KZPCA devices, which resulted 
   in a syncrhonization problem, causing the SCSI bus to hang. Sense data was 
   potentially lost because the autosense command was being queued at the tail 
   of the request queue.

2) The event logger will report command timeouts. 

3) Problem with the KZPCM driver.  A panic, machine check, or hang 
   can occur when aborting an I/O due to a command timeout or aborting an 
   application program with pending I/Os

4) Problems with the ITPSA driver that supports the KZPCM adapter.  The 
   following problems can occur while the system is processing a
   SCSI bus or SCSI bus device reset request that is issued from the class 
   driver:

   A. The following ITPSA events are logged in the /var/adm/binary.errlog file
      or the /var/adm/messages file:
         a. Command timeout
         b. Illegal instruction
         c. HTH timeout
         d. SCSI bus reset error
   B. The system panics and displays the message "xpt_callback: CCB NOT ON ANY
      LIST"
   C. The system panics and displays the message "simple_lock: TIME LIMIT
      EXCEEDED"

5) Problem on the 8951U and 8952U adapters.  SCSI bus resets are lost when 
   these adapters are connected to single ended drives.


PROBLEM:  (QAR 72008)    (Patch ID: OSF435-377)
********
This patch fixes a simple lock timeout panic.  It was possible for a bus
reset to be generated before the previous bus reset was processed,
causing excessive processing within the ISR.

PROBLEM:  (QAR 74525)    (Patch ID: OSF435-377)
********
This patch fixes a kernel memory fault panic caused by a SWS data structure
being released twice.

PROBLEM:  (QAR 72879)    (Patch ID: OSF435-377)
********
This patch fixes a problem where the chip interrupt register fields in
the error log are incorrect.

PROBLEM:  (QAR 73998)    (Patch ID: OSF435-377)
********
This patch fixes a problem where an error message was being
logged for a condition, which is not a true error.

This patch fixes a lockmode 4 panic on boot.
