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@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.
