we saw this "problem" last week actually.  a new instal dual core
duo machine was installed with a 32-bit version of suse 10.  srp ran,
but sometimes the scsi data buffers had minor single byte errors (they
didnt appear to be at page boundaries but i am not certain about 
that).  perhaps a kmap issue?  64-bit machines running 32-bit/PAE
with more than 4GB of memory?

this is anecdotal evidence of course.  we were (are) seeing symbol
errors on the cable but i should think these errors get as far as
the srp layer.
