IV83138: ASSERT IN DL_LIST_DESTROY_SANITY APPLIES TO AIX 7100-03

APAR status

• Closed as program error.

Error description

• An assert is hit when doing an rmdev of a device that
  uses mlxentdd as the driver.  The stack is:

  (000000000000028E [??])

  This occurs only after the driver gets into an unstable
  state following an open that failed midway through.
