[c-nsp] 7600 sup7203bxl error msg

[matt carter]

hey all,

hoping someone may have an insight into some errors i have not seen before

Nov  7 11:24:46.535 AEST: %SYSTEM_CONTROLLER-SP-3-ERROR: Error condition
detected: TM_DATA_PARITY_ERROR

Nov  7 11:24:46.535 AEST: %SYSTEM_CONTROLLER-SP-3-EXCESSIVE_RESET: System
Controller is getting reset so frequently

first one is fair enough

Explanation    The most common errors from the Mistral ASIC on the
supervisor engine are TM_DATA_PARITY_ERROR and TM_NPP_PARITY_ERROR. Possible
causes of these parity errors are random static discharge or other external
factors.
Recommended Action    If the error message is only seen once (or rarely),
the recommendation is to monitor the switch syslog to confirm the error
message was an isolated incident. If these error messages are reoccurring,
open a case with the Technical Assistance Center

but the construct of the second error seems to suggest this is not a
"isolated incident" since my system controller is being reset "so
frequently" which kind of makes the log messages somewhat contradictory in a
fashion. when i go looking at the SP stack i can only see the mistral error
interrupt called once.

from show stack
Interrupt level stacks:
Level    Called Unused/Size  Name
  5           1   7168/9000  Mistral Error Interrupt

when i check the ibc stats i can see the mistral hardware was definately
reset at the time of the incident, and has 
been reset 3 times, but there is 0 errors. 

anyone have ideas on how to proceed in terms of catching this if it happens
again?
