Also the changes to sys/arch/sgi/xbow/xbridge.c did not helped, the problem persists. I attached the patch with the changes I created. First I commented out the stuff in the first hunk, afterwards also changed the stuff in the second hunk. I hope I changed the if statement in the right place since I found it multiple times in the file. Sebastian [demime 1.01d removed an attachment of type text/x-patch which had a name of xbridge-patch]
