PROBLEM: (BCSMC0SLW, BCGM70KGG, BCGM10MCB, TKTBC0076,
          77220, 75146) (PATCH ID: OSF445-199)
********
This patch fixes an incorrect heartbeat timer within the memory channel driver
which caused rail failures to be incorrectly reported on memory channel version
2 cards.  With the heartbeat timer set too short, the system can be erroneously
led to believe a hardware failure has occurred.  Messages of the form
"rmerror_int: ..." are output to the messages file containing an error_type
which has bit 29 set in error_type (heartbeat timeout).  The binary errorlog
will also have this data.  Typically, the error_type data will be 0xe00000000.
The messages are followed by the system hanging or panicing.  When panicing,
the following message is produced:

panic (cpu 0): rm_failover_if_necessary, both rails bad

A real hardware failure produces the same symptoms and stack trace.  For
example, having an error_type of 0xe00000002 indicates a write transmit
hardware fatal failure.
