Oops, forgot to tell - Chris Mason's patch has been applied (so NO change). The problem seems somhow related to the general kernel lock in ioctls - to prove I commented the unlock_kernel()/lock_kernel() in sock_ioctl out, leaving the kernel locked during socket ioctls - bad, but proves ioctl related locking problem in ppp_generic.c... The problem has nothing to do w/ double frees or mem. corruption (IMO) - it seems to be related to "rest of the spin lock abuses" in ppp_generic.c... :-)
Thanks for your help
