SubjectRe: [BUG]: 2.4.10 lockup using ppp on SMP
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
