mpt driver problem?

[Bruno Afonso]

Hi,

I have a box that's running a scsi card that uses the mpt driver. This 
is now running 6.0:

The problem appears randomly on boots, meaning that it does not show 
indeed on EVERY boot, but afterwards, every so often. This is what 
typically appears:

I'd like to know if this is a serious problem with hardware or the 
driver itself. Should I worry? I know that some work is being done on 
mpt but I cannot use -current as this is a production box. I have used a 
-stable and it didn't improve so now I'm back to 6.0. I'll provide more 
information if needed.


Thanks
