-
- Well, I haven't had any kernel hangs or crashes in my system since I added
- Jolitz's fixes (kmap entries and buf pages). However, I have noticed that
- something is wrong with the way that 386BSD handles a math coprocessor.
-
- With the fixes to make ps work (adding symbols etc...), ps works on several
- 386's with no math coprocessors, but receives a floating point error on
- a 486-33.
-
- Any ideas? I haven't had the time yet to dig into it. I've been getting
- X386 running. X is a good thing. :-)
