I had the same experience, and worked with Stefan to figure it out. He told me to take the flags in ncr.c line 3329 (the ones defined for the 825A) and remove them one by one to see what the trouble was. Many builds and reboots later, I told him it was the FE_RAM flag. He said that was highly unlikely, and to see if I could swap out the 825a for another one. I did, and he was right, swapping it out fixed it. I think I may be close to you ... if we can work it out so I'm out of service a real minimum amount of time, I'd swap with you.... see, I'm doing some very heavy development, and wouldn't think of it if we weren't in driving distance. You see my address/phone below. Let me know if you want to do this. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
