BMC ROMB Battery voltage sensor state asserted

[Robert Parsons]

With increasing frequency I am finding these errors in the ESM log 
(PowerEdge 2850 running Debian Linux)

BMC ROMB Battery voltage sensor state asserted

followed a few minutes later by

BMC ROMB Battery voltage sensor state deasserted

When this occurs the disk performance goes to pot and the machine 
ultimately fails because of this. I suspect that the cache is being turned 
off but apparently it is not being turned back on.

Can you confirm that the cache is turned off when this condition 
occurs?  Should it be turned back on automatically when the fault is 
deasserted?  Is there any way to prevent this from occuring?

Thanks.
