But I'm getting it too. One minor nit: obviously you are running beyond the 16 MB boundary. But your dmesg output shows only 16 MB. I'm guessing that you've disabled the other half in order to get the machine to run. Is there anything else in the dmesg output which is less obvious? I'm forwarding this to the SCSI mailing list, where I just sent a similar message describing my own problems. If there's anybody else out there on -questions who are having this problem, please let us know.
