Here's the last 50 lines of the external adapters event log.  Unfortunately it looks like one of the admins here cleared the log on the other controller. :(   Tho I'm sure in the next few days I'll have something there. :)

Adapter: 0 - Number of events : 8791

Sense key B/4B/4 is a buffer overflow error going by the tool I have here:
Full KCQ Dump
KCQ: B4B04

Sense Key:Volume Overflow:
Indicates a buffered peripheral device has reached the end of medium 
partition and data remains in the buffer that has not been written to 
the medium.
Key Code:KCQ code unknown

Could the IO errors be coming from the Perc6E for the storage?

It would be interesting to see a controller log (use megacli to get the 
controller logs for the internal and external controllers assuming a 
perc internal controller as well).

David.
