After a Unibus reset, our UDA50 gets thoroughly hung. (We're running 4.1BSD on an 11/780.) The symptoms are that we get a UBA IVMR error with FUBAR = the address of the UDA50. At this point, the UDA50 timeout routine I added starts resetting the UBA once every 20 seconds. (And then when the UDA50 interrupts, we get another IVMR error, etc. etc.) It looks to me like the UDA50 driver reset routine is screwing with some UBA thingy that it ought to be leaving alone. Has anyone else encountered, or better yet fixed, the problem? -- In-Real-Life: Chris Torek, Univ of MD Comp Sci UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris.umcp-cs@UDel-Relay
