After about a hour of playing around with 0.95, I've found a couple
of problems. Here's my configuration:
- kernel built from source, using GCC 1.40. (I don't have access
to GCC 2.0.)
- otherwise I'm using a 0.12 system, i.e. no changes in libraries, etc.
1) system hung, probably in serial or tty code. I was experimenting
with performance of SLIP. So all I was doing was serial I/O and
screen display. When I increased the TCP window size to 1024 the
system hung, having displayed a few lines of garbage on the screen.
The obvious suspicion is that the serial code can't handle getting
more characters than its buffer size. I tried increasing the tty
buffer size to 2048.
2) I was unable to rebuild the system under 0.95. gcc claimed it saw
unterminated conditionals. There were other signs of problems with
the hard disk during this: "Unexpected HD interrupt". I tried
removing the warning message and reset.
3) While trying to FTP in the image of the root disk, I got a panic
"free_page_tables called with wrong alignment". At this point I would
have been doing serial line I/O and a small amount of disk I/O
(writing the file).
I've backed out of testing 0.95 for the moment.
