Ok no one has responded to that bug ... :/
On a system lock up I ssh into the box and saw wait time was 83% in top.
I also saw that kcrypd was using 23% of cpu time - and that only one
core was in use.
1012 root      20   0     0    0    0 S   11  0.0  30:15.46 kcryptd

The system was stalled for 20minutes ...

load average: 19.16, 15.74, 11.43
