Alexey,
Hmm. Thanks. Not at all sure how that happenned. You seem to be right
though, when I specify the System.map I had in /boot for that kernel (which
_should_ have been the same as in /usr/src/linux, sigh), I get something
that looks a lot more like the old tcp_keepalive crash that's been dogging
me (from 2.2.13 on) since last Fall. Results below.
Oleg's patch, by the way, didn't take. I've currently switched to the
2.2.17pre5 kernel to see if the fixes there work for this. Since the usual
case is for it to take a week or so to crash, I can't say if they matter
yet.
