[CentOS] ATA: abnormal status 0x7F on port 0xB887

Hello,

We have recently purchased two Supermicro servers, AS-1021M-T2RB
(http://www.supermicro.com/Aplus/system/1U/1021/AS-1021M-T2RV.cfm), and
have built them both with CentOS 5 operating system. They are identical,
apart from the manufacturer of the disk drives.

Kernel is: Linux version 2.6.18-8.1.6.el5
(mockbuild at builder6.centos.org) (gcc version 4.1.1 20070105 (Red Hat
4.1.1-52)) #1 SMP Thu Jun 14 17:29:04 EDT 2007

Both servers have 2 SATA disks, and using software RAID 1.

When they boot, we see this error in dmesg:
 ATA: abnormal status 0x7F on port 0xB887

The servers seem to be working OK, but we're a little worried. The full
dmsg is below. Is anyone able to help explain what this problem/message
could be?

Thank you.
