The subject system is a 4/470 whose CPU has been upgraded to rev -12, and whose OS has been upgraded to 4.1.1, in response to Sun's claim that the problems with intermixing IPI, SMD, and/or xy472 controllers would be solved by making those changes. This system does not have a Sun-supplied 7053, however. It has Xylogics 7053-106-211s (with 2.23 PROM) in slots 10 and 11. (Xylogics tells us 2.23 is the latest rev; I don't know if it is equivalent to Sun's 501-1249-04 level SMD.) The Xylogics 472 is in slot 9. When a tape is written and read back, we see spurious interrupt messages: spurious VME interrupt at processor level 9 VME level 5, VME vector 0xffffffff usually accompanied by a message from the xt driver: xt0: stray interrupt Has anyone out there (esp. those who are using 3rd-party 7053s) been able to run a xy472 in your 4/400 without the spurious interrupts? If so, what is the solution? Please respond directly to me if you have any info; will summarize. Thanks in advance ... era@ncar.ucar.edu
