Good morning.
I'm getting these oops every six hours approximately
The oops is always at dispose_list+114.
I am using encrypted swap. I tried both encryted swap over loop and
direct encrypted swap.
I will try unencrypted swap next.
My machine is an AMD64.
I'm aware there are a lot of changes mentioning swap in 2.6.17.preX.
I will test 2.6.17 when it comes out if I receive no reply.
I hope these can be of use in debugging kswapd.
If there is something you'd like me to test, just ask.
R.
Oops:
