In principal it means that the skb is still queued somewhere when caller
tries to free it. In practice, it frequently indicates that a dangling
skb pointer or a pointer not related to an skb was passed to
kfree_skb(). That's probably what's happening here. The kernel
crash symptoms you describe are also typical for such class of bug.

It also indicates that the bug is probably not inside isdn_ppp, but
somewhere else (in the lower isdn layers, or even somewhere totally
unrelated).

BTW, is your kernel SMP?
