Hi, I'm having the same trouble with this card as everyone else. I'm 
wondering if anyone would care to comment about what the above patch may 
break.  Is it going to disable safeguards, such that if a disk in my 
system actually does crash, I won't know it?  Or, is it simply going to 
mean that I should be careful to only plug things into the system that I 
know are supported?

I'm in contact with Gigabyte, trying to get their opinion on the 
matter.  I know others have said that they are very unhelpful when it 
comes to linux support, but I'm hoping that if we can show them what's 
wrong, they could roll up a fix in a firmware release.
