This does not sound like a simple failed disk. We also use Areca RAID 
controllers, they are great, and a failed disk does *never* influence 
the running system - that's what you have the RAID controller for, after 
all. You only receive an e-mail from the controller about the disabled 
disk.

The "isr got aborted" sounds like a driver problem, please report that 
log snipped to areca support so they can help you (I'd be interested in 
the results too - please tell me per PM once you know). The address is
support at areca.com.tw, and they tend to answer quickly and good.
