As you can see, they are sporadic, and don't seem to be causing any
problems.

I have a Symbios SCSI card installed in a PCI slot, but I've yet to
connect any drives to it.  I'm wondering if that could be the source
of "interrupt level 4 not serviced".  Any clues on the M_IOCACK
message?  I imagine it would be the hme ethernet?

Maybe you could do a search for glm on the access1 web site and see if
any of the updates from 2.6 fixed this warning or at least documented
it.

Hi,

Looks like this is a known bug. It does seem to have to do with the SCSI card and can also be caused by the PGX grahics card. There is a bug filed and a fix should be forthcoming. It doesnt appear to effect the system other than filling up your messages file.

cheers,
