Hi Michael,
Although i do not use EVMS yet i've too experienced similar I/O
errors (I/O error in filesystem ("sd(8,3)") meta-data dev 0x803 block
0x1990a0^I ("xfs_trans_read_buf") error 5 buf count 8192)
on SCSI drive attached to AHA-2490U2W controller.
It turned out to be a loose card in it's PCI slot that was causing
these errors on my box, so perhaps you should try to check the
hardware first and see if all the connections,cables are good...

Paul B.
