Masa has clarified this as an issue specific the IPMI for the onboard devices 
on the
H8SSL (SuperMicro) and likely other boards.  I saw this behavior in 5.x testing 
as well,
but it looks like it has been addressed in -current.  Running 6.99.19 on the 
same host
showed the bge driver to be robust.  If possible, it would be great to have the 
-current
bge code, if it is not too extensive of a change, in the pending release of 
6.1.  

Thank you for your clarification and help with this issue.
