Error messages in dmesg

[Morten W. Petersen]

Hi,

hopefully I'm asking in the right list..  I have a remote FreeBSD system
that has a RAID configuration, and recently I got the following message
in dmesg:

SIMODE0[0xc]:(ENOVERRUN|ENIOERR)
CCSCBCTL[0x4]:(CCSCBDIR)
ahd1: REG0 == 0x1f, SINDEX = 0x122, DINDEX = 0xe1

is this something I should worry about?  How can I interpret
"info:4005", "asc:40,82" and so on?

Thanks,

Morten
