All three are a bit dated and likely noone has ever tested that
combination before.
Can you upgrade to something more current? kernel 2.4.21-pre5 should
work out of the box, I would guess.

There is little point in fixing a problem _again_. :)

Don't know, didn't look at the code. But it appears as if
recalc_sigpending has been changed sometime and one of 1), 2) and 3)
has the new version and another one the old one. Just a guess.

If you want to fix it yourself, look at fs/jffs2/background.c and
search for recalc_sigpending in http://lxr.linux.no/ . But upgrading
sounds like the better option.
