"parity error" in a SCSI board

["Oliver Schulze L." <oliver samera com py>]

Hi,
I'm running RH9 and noted this error en /var/log/messages:

"kernel: (scsi:A:6:0): parity error detected in Status phase. SEQADDR(0x7f)
SCSIRATE(0x88)"

The SEQADDR change with this values: 0x9e, 0xa5, 0x82

The Adaptec card is: AHA-2940 U/UW/D AIC-7881U

The mobo is an ASUS P4S-533-MX running a Pentium 4 1700Mhz

Anyone has seen this message? I want to know if this is a critical data 
loss error.
I also have seen this error during install of RH8.0 in the same machine.

Many Thanks
Oliver
