We have multiple systems using LSILogic PERC4 cards (PERC4e/Si, 
PERC4/DC, amr driver).  After recently upgrading two of them from 6.3 to 
7.1, we have begun to see the following errors in our logs during heavy 
use in both systems:
amr0: Too many retries on command 0xffffffff80a4da58.  Controller is 
likely dead
amr0: Too many retries on command 0xffffffff80a4eaa8.  Controller is 
likely dead
amr0: Too many retries on command 0xffffffff80a497a0.  Controller is 
likely dead
amr0: Too many retries on command 0xffffffff80a4eaa8.  Controller is 
likely dead

However, the system continues working and the volumes remain 
accessible.  This happens on the PERC4/DC controllers in both systems.  
Firmware version is 352D.  MegaCLI reports no problems.

Has anyone else seen these messages?  A google search turns up nothing 
but results in the driver code.  Is this something we should be worried 
about?  We won't be moving any other systems to 7.1 until we can clear 
this up.

Thanks!
