I have upgraded my cube to NeXT OS 2.0 with the 68040, added memory and some peripherals- and have been getting some spooky intermittent problems. I was wondering if anyone else has experienced these problems and could suggest solutions. FIRST, I added a PLI drive in a SCSI chain that goes from an external HD, to the PLI drive, and then to a scanner. I seem to lose the PLI drive periodically with zillions of repeated messages like: Mar 30 10:15:47 ljkiraly mach: sd2 (4,0): ERROR op:0x0 sd_state:2 scsi status:0x0 Mar 30 10:15:48 ljkiraly mach: sd2 (4,0): ERROR op:0x0 sd_state:2 scsi status:0x0 Mar 30 10:16:17 ljkiraly last message repeated 24 times These continue until I power cycle the PLI drive. I added an external SCSI line terminator to the scanner (which is supposed to be internally terminated)- which has seemed to help but not solve the problem. Any suggestions? SECOND, I get a lot of console messages like: Mar 29 10:39:33 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=5 Mar 29 10:43:20 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=7 Mar 29 10:45:11 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=10 Mar 29 10:50:18 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=12 Mar 29 10:52:37 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=15 Mar 29 10:53:56 ljkiraly Workspace[1195]: cheap: dropping extra collection sequence=17 Theses messages don't seem to effect anything directly- but I worry about them because THIRD, I periodically core dump when logging out. I have also experienced a number of problems when logging in as root and having problems launching standard apps like Terminal- these apps go into a launching status and never complete. I have to kill them from a processes window- and I cannot launch them again until I logout and login again. Finally, on a few occasions I have gotten alert panels on logging in that describe an "internal error- continue at your own risk" kind of message- to which I respond be either rebooting or power cycling the machine. Is anyone else experiencing these problems? Any recommendations? I really lover my NeXT- but find these problems a little aggravating, since I never experienced them with my slow '30 version 1.0 system. -- ___________________________________________________________________________ Jim Kiraly - jim@ljkiraly.lerc.nasa.gov - NASA Lewis Research Center ---------------------------------------------------------------------------

Apparently you cannot connect Mac PLI drives to the NeXT without a ROM and jumper change because they do not fully uphold the SCSI Standard. Call PLI for details. - Jiro Nakamura jiro@shaman.com ps.

Call PLI for details. -> -> - Jiro Nakamura -> jiro@shaman.com Nope, it's a NeXT external PLI drive. I have been getting some other spooky console messages as well- so I am going to take everything out of the SCSI chain instead of the PLI drive and then wait_n_see... Next, I will probably put all the SCSI stuff back except for the PLI drive. The darn thing about all this is that it is an intermitant problem. So far only one other person has noted a similar problem with no fixes yet! -- ___________________________________________________________________________ Jim Kiraly - jim@ljkiraly.lerc.nasa.gov - NASA Lewis Research Center ---------------------------------------------------------------------------

SCSI problems are often difficult to diagnose because of the lack of diagnostic software. Does anyone know of any good SCSI diagnostic software for the NeXT computer? :-( Joe jchin@van-bc.wimsey.bc.ca -- ************************************************************** * "Kill the body and the head will die" (Hunter S.
