100VG-AnyLAN and HP-PB 100Base-T Error Messages
SDI Driver Specific Status Values
5150 CLAS0001 MESSAGE: Driver encountered a hardware problem.
CAUSE: While attempting to alter 10Base-T loopback mode during
diagnostic testing of a 100VG-AnyLAN adapter card, the driver read
from a PHY control register in the LAN controller chip of the card, but
encountered an error. Most likely the chip has failed, but a power
failure may have occurred (“Cause” = 32-bit status returned by the call
to vg_mii_read16).
ACTION: If a power failure has actually occurred, this error can be
ignored; the driver should recover automatically. Otherwise, the MII
bus may have failed; replace the adapter card. If the same problem
persists, see Appendix A , “Submitting a CR.”
5180 CLAS0001 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 (“Cause” is not used here). The state of all transmit
queues was not one of the legal states predicted at design time.
ACTION: This is a fatal software error. The driver will not attempt to
continue. 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, first activate link tracing, reproduce the problem,
stop tracing, and save the resulting link trace file. Then see Appendix
A , “Submitting a CR.”
5210 CLAS0001 MESSAGE: A data buffer is too long.
CAUSE: During diagnostic loopback testing, the driver was asked to
prepare a data block for transmission, but the block length or memory
allocation was beyond the driver’s DMA capabilities (“Cause” = 32-bit
total length of the requested transmission).
ACTION: This problem should only be seen in diagnostics, however it
should not be occurring at all. Specify a shorter loopback length, and
see Appendix A , “Submitting a CR.”
5240 CLAS0001 MESSAGE: Driver encountered a software problem.
CAUSE: While beginning a 100VG-AnyLAN link training sequence, the
driver started to reset the PHY chip, but encountered an error while
trying to get or reset a timer (“Cause” = 32-bit status from the call to
vg_start_timer). This timer was to be used to wait for the PHY reset
to finish; the driver cannot connect the link if a PHY timer cannot be
started. If this error is reported, it is because the driver has already
encountered some other error.
ACTION: Typically preceded by another error message giving better
information about the original cause; check log data for that error and
look it up also. The driver did not dump, but will still attempt to
auto-reset itself, up to a total of 12 times or more.
