I have heard that I shouldn't be
running the development kernel, but if
no one does, it'll never be fixed,
besides, I like it's features. Anyhow,
my problem is that when my modem dies
during a connection(the isp drops me,
my line goes dead, someone cut my phone
line), ppp0 stays "connected" even when
running /sbin/ifdown ppp0. When I try
to remove ppp0 from ifconfig, the
kernel spits at me saying there is a
kernel bug in spinlock.h. I first
noticed this in 2.3.38 and it is
currently still alive in 2.3.40, I
haven't had a chance to check 2.3.41
yet, but I will do that later today. I
compiled pppd against 2.3.38 and I
don't think it matters what version of
pppd I am running, but if you need
that, I can get that too. Here is what
is dumped from the kernel when I kill
pppd on a frozen connection:
