- I have installed setup my kernel to make symmon available
- according to the instructions in "IRIX Device Driver Programming Guide,"
- Document Number 007-0911-020, 3/92.
-
- When I enter symmon by typing ^A and then type:
- kp scsi 0
- I get:
- WD93A controller at 0xb7f08007
- AUX 0x0 ...
- .
- .
- .
- CMD 0x8 DATA 0xff <and then it hangs right here>
-
- What I mean by <and then it hangs right there> is that the cursor
- is left at then end of "0xff" and no newline seems to be output.
- Not only that, but now symmon is dead, and ^A will not bring it back.
-
- Is this a known problem on Crimson, or is there something
- wrong with my IO3 board?
-
- Where "*" above indicates characters written in by hand with ink,
- identification numbers on my IO3 board read:
- *** * ******
- ...ASY 030-022-002 Rev B DA#675
-
- The two chips that I think are the WD33C93 chips are marked
-
- AM33C93A - 16PC09
- 208NVLD
-
- and the chips I think, but am less sure, are proms used with the
- controller chips have stick-on labels reading:
-
- 0700703001
-
- Background info:
-
- We have a timing - related problem that may be a bug in IRIX or
- in our specific hardware that is evidenced by a temporally tempramental
- set of: 6 x read(80 bytes), ioctl(forward space file), n x read(8192 bytes),
- ioctl(forward space file) 6 x read(80 bytes). And that is why I want
- to know whether "kp scsi 0" is supposed to work.
-
- Oh yes, the Crimson passes all diagnostics we have run. Of course there
- doesn't seem to be much documentation on them so it is hard to be sure
- we are using them correctly.
-
- Kudos to anyone who has even a single photon of light to shine on this
- problem.
