Below is a description of a known ppp-2.3.5 problem and a cure. There was
a lot of discussion about it here a short time ago. I have good reason to
believe that everything said below is correct.

If you have such errors then, whatever the reason or kernel version, the
cure should be the same. With a pristine ppp-2.3.5 source tree, starting
at line 3079 in ppp-2.3.5/linux/ppp.c you have:
#if LINUX_VERSION_CODE < VERSION(2,1,86)
#define FREE_SKB(skb) dev_kfree_skb(skb)
#else
#define FREE_SKB(skb) dev_kfree_skb(skb, FREE_WRITE)
#endif
Change the "<" to ">=" . Then copy the modified file to the kernel
source directory /usr/src/linux/drivers/net, replacing the old ppp.c
there, and recompile the kernel. The cautious may want to save the
old kernel ppp.c first.
If the particular Linux distribution you use has chosen to modify ppp.c,
you still should be able to use this as a guide to find this code near line
3079 and change it.
