SDI Driver Specific Status Values
125 ($7D) MESSAGE: Driver has detected data corruption.
CAUSE: A driver receive-frame DMA operation completed, but in doing
a quick check of the DMA’ed data, the driver found all ones in the first 4
words, indicating some kind of driver/ adapter card bug has occurred.
Probably the driver attempted to perform a DMA transfer which was
not a 4-byte multiple in length.
ACTION: This is a fatal error. The driver has halted all operations to
prevent mishandling any user data, and did not forward the received
frame to upper layer protocols. The driver will now attempt to perform
a dump of all host context data structures and adapter card memory,
then reset itself and continue. Save the resulting NETDMP##.PUB.SYS
dump data file for analysis by Hewlett-Packard. See Appendix A ,
“Submitting a CR.”
126 ($7E) MESSAGE: An unexpected transmit condition was encountered.
CAUSE: While attempting to initiate DMA to send some transmit data
to the adapter card, driver software found its data structures to be in an
unexpected state. The state of all transmit queues was not one of the
legal states predicted at design time.
ACTION: This is a fatal software error. After reporting this error, the
driver will die, then will either attempt an auto-reset or else require a
manual shutdown and restart. If the problem persists, take a link trace
of the problem, then see Appendix A , “Submitting a CR.”
128 ($80) MESSAGE: Illegal access to saved port message area.
CAUSE: While completing an old blocking request (requiring a driver
exit and later reply), the driver found that the entry in the pending
message save area, where the request was supposedly saved, was no
longer in use, or was not within the range of legal table indexes.
ACTION: This fatal software error is only caused by a bug or memory
corruption, because the driver should never be trying to complete the
same message twice, or passing an illegal index. After reporting this
error, the driver will die, then will either attempt an auto-reset or else
require a manual shutdown and restart. If the problem persists, take a
link trace of the problem, then see Appendix A , “Submitting a CR.”
129 ($81) MESSAGE: Frame received when no queue entry was available.
CAUSE: When processing an interrupt for a received data frame, the
driver was not able to locate the adapter card data memory frame
containing the data. The driver thinks there are no more adapter card
memory frames in which to receive incoming frames, yet the card has
reported another frame anyway. The driver is designed to maintain
synchronization with the card, therefore it appears that either an
out-of-sync condition exists, or the card has a problem.
ACTION: The driver acknowledged and dropped the interrupt and the
received packet. Many upper layer protocols typically retransmit lost
