>Release:        OpenBSD 2.9 RELEASE (also CURRENT)
>Environment:
        Dell PowerEdge 2500SC w/ PERC 3/Di Raid controller, OpenBSD 2.9
fresh install from CD
        System      : OpenBSD 2.9
        Architecture: OpenBSD.i386
        Machine     : i386 (Dell Powere
>Description:
	During install and use of machine, the error (on blue background):
	sd0(aac0:0:0): timed out
	occurs.
>How-To-Repeat:
	Error seems to occur randomly, more during heavy disk usage and
	CD access (happened several times during the install copying files
	with *********, the copying will freeze for about 15 seconds, then
	the error will appear and it will continue to copy).
>Fix:
	Does not seem to hurt normal system operation.

Here is the dmesg:
