Hi
i opened file /usr/src/kernel-source-2.xxx/drivers/net/eepro100.c
which has arround 150 lines of comments. at line 184 or so.. . Emacs stops
changing the color (global-font-lock-mode) of comments after certain point
( 100 lines or so) after that it shows the comments as normal text and
highlights the keywords such as "do" "for" etc..
One more thing i noticed i selected whole buffer and said "indent-region"
Now everything is fine..
Why emacs is unable to see the comments as *comments*
I am running 21.3.1

My crystal ball says that you have an open-paren or open-bracket or
open-brace in column 0 somewhere inside your 150-lines-long comment.
Emacs thinks this indicates a "beginning of defun" and thus assumes
it's not inside a comment. This heuristic is used in some cases but not
all the time, so the highlighting will sometimes be correct and sometimes
not depending on where the font-locking has started (since you're
presumably using jit-lock which highlights the buffer on the fly in small
increments).

Got no idea what causes that, but M-x lazy-lock-mode RET fixes it
Bug in jit lock? I don't even know if its gauranteed to work in all situations.
