I've been having a problem since 5.3 days (currently on 6.0-RELEASE  
some p level) that happens very infrequently (every couple of weeks  
to every couple of months)  that looks to be the same thing.  I am  
not creating my md devices using option async.  In reading the CVS  
log for rev 1.115 it seems that async was turned off as the default  
to avoid this problem, and that if I am suffering from the same  
problem, I shouldn't be as sync is the default now on md creation.   
Am I reading this correctly?

Thanks
Chad
