PHNE_11510: OTHER Data loss. Backplane DMA timeouts. PHNE_10778: PANIC PHNE_9285: PANIC Path Name: /hp-ux_patches/s700_800/10.X/PHNE_19232 Symptoms: PHNE_19232: DTS TPO0h01967: Some ports on some 8-port cards fail to come up in X.21 mode. DTS TPO0h02414: A customer would like to be able to congigure the frame protocol buffer transmit timer in the same way timers are configured in HDLC-LAPB. A problem exists at baud rates of 1200 and below. A full buffer of data (238 bytes) will be cut short when the 1 second transmit timeout expires. DTS TPO0h02429: The ACC loopback test (invoked by the LB command in zmntr) was occasionally failing with non-defective 8-port cards. The problem occurred on average about once every 50 zmntr LB commands. DTS TPO0h02504: With the baud rate incorrectly configured as 64,000 while the actual line speed is 9600, transmitted frames can be cut short and joined together. DTS TPO0h02773: Some ports on some cards do not work properly in X.21 mode on the 8-port NIO and EISA cards. Some of these failures occur just after a card reset, and recover after some 10 - 30 seconds. Other ports fail all the time. The failure appears to be the port detecting the CTS and/or DCD signals missing. PHNE_17260: SR 4701405889 / DTS TPO0h02414 The Z180 based cards timeout when sending a buffer larger than 147 bytes at 1200 Baud rate. SR 5003385856 / DTS TPO0h01587 /opt/acc/sys/z7400_rom.zsnp not updated by PHNE_11510 PHNE_15369: SR 4701391862 / DTS TPO0h01966 No current method to determine hardware revision PHNE_11510: SR None / DTS TPO0h01418: Back Plane DMA timeout. And application-generated data traffic's inability to be sent out the line. PHNE_10778: SR 4701349928 / DTS TPO0h01198: System panic or DMA timeout occurs occasionally during ACC start up while downloading EISA ACC card. PHNE_9288: No ACC Base FW (EISA) related symptoms for this patch. PHNE_9285: SR 4701344473 / DTS TPO0h00994: DMA timeouts and system panics can occur when the EISA ACC is used and the onboard LAN interface is busy on some D-class and C-class systems. PHNE_9284: No ACC Base FW (EISA) related symptoms for this patch. PHNE_9283: No ACC Base FW (EISA) related symptoms for this patch. PHNE_8991: No ACC Base FW (EISA) related symptoms for this patch. PHNE_8833: No ACC Base FW (EISA) related symptoms for this patch. Defect Description: PHNE_19232: DTS TPO0h01967: Change to ensure that X.21 is disabled for the Z7200A Rev.A card only. Change particularly focused at the Z7400A EISA cards to ensure that Rev.A cards are not disabled from X.21 configuration. This corrects the X.21 configuration problem with all cards. DTS TPO0h02414: The transmit timeout is fixed at 1 second which is not enough to allow the complete transmission of a full buffer (238 bytes) at 1200 baud or less. The frame module now sets the timeout according to the configured baud rate on the port. Baud rate Tx timeout (x100ms) 300 136 600 69 1200 35 2400 18 4800 10 9600 6 >9600 4 These timeouts allow approximately double the necessary time for the maximum of 252 bytes to be transmitted. 252 bytes is the maximum number of bytes to be transmitted because that is the maximum which can be held in one ACC buffer. DTS TPO0h02429: A problem with the 8-port's ISCC chips caused a transmit underrun to be incorrectly generated during the start of a frame tranmission - resulting in the first few bytes of that frame being corrupt. Note: The test is transmitting in single character mode. On initialisation of the ISCC, the firmware was issuing a "Reset Tx Underrun/EOM Latch" command. This was found to cause the occasional transmit underrun external/status interrupt. This reset command was taken out of the initialisation sequence in the testprot firmware. DTS TPO0h02504: This is due to an enhancement that was made for defect TPO0h02414. The transmit timeout used at level-1 was shortened for baud rates as high as 64000. Because incorrect baud rate configurations can lead to this problem, part of the changes made for TPO0h02414 have now been backed out. The minimum timeout used is now 1 second which will allow for typical incorrect configurations. DTS TPO0h02773: The Sipex chips (line drivers) when placed in RS422 mode (balanced signaling mode used for X.21) leave some unused TTL output pins in an unknown state. These pins are used for the CTS signal when the Sipex chip is in RS232 mode. The firmware was reading the state of the CTS signal - and the ISCC chips were configured to react to this signal. This problem was not detected before because the usual state of these Sipex pins signal that CTS is up. On some Sipex chips, this signal is down, or is down and then comes up after a short period of time after being put into RS422 mode. The firmware has been changed to ignore the CTS signal when in X.21 mode. Also the ISCC chips are configured to also ignore changes in the CTS and DCD signals. The firmware code still checks the DCD signal - which matches the X.21 Indicate signal, so the firmware still can detect a cable disconnect. Note: There is no problem in ignoring the (internal) CTS signal - as it does not map to any signal in X.21. PHNE_17260: SR 4701405889 / DTS TPO0h02414 The Z180 based cards cannot transmit more than 147 bytes at 1200 baud, because the transmit timeout is set at 1 second per buffer and it takes more than 1 second to transmit 148 bytes at this baud rate SR 5003385856 / DTS TPO0h01587 PHNE_11510 did not update /opt/acc/sys/z7400_rom.zsnp PHNE_15369: SR 4701391862 / DTS TPO0h01966 Enhancement to detect hardware revisions of ACC cards. A standard interface has been defined to identify hardware revisions of all ACC cards. The 'mx' command of zmntr has been enhanced to include the display of the hardware revision. PHNE_11510: SR None / DTS TPO0h01418: ACC EISA card firmware defect. PHNE_10778: SR 4701349928 / DTS TPO0h01198: The EISA ACC firmware was not checking for an empty fifo condition while using programmed I/O to read an immediate mode command from the hp-ux host. PHNE_9288: No ACC Base FW (EISA) related defects were fixed in this patch. PHNE_9285: SR 4701344473 / DTS TPO0h00994: The ACC firmware was not correctly setting up the logic which controls the data transfers from the EISA bus into the ACC card memory for host to card transfers. The logic would fail to stop writing to the ACC card memory when the data transfer over the EISA bus was paused. When the onboard LAN was busy, the transfers to the EISA ACC card could be slowed causing the problem to appear. PHNE_9284: No ACC Base FW (EISA) related defects were fixed in this patch. PHNE_9283: No ACC Base FW (EISA) related defects were fixed in this patch. PHNE_8991: No ACC Base FW (EISA) related defects were fixed in this patch. PHNE_8833: No ACC Base FW (EISA) related defects were fixed in this patch.
