surerecommended method now is to upgrade to BOINC 6.6.20 and to use its scheduling abilities instead of "teamed" pack.
Already running 6.6.20. 
Just wondering about the cuda frozen task kill.
The same here: updated to 6.6.20 and frozen task. 
Should we combine 6.6.20 with v11? 
Yes, you could try (it's experimental software so "could" and "would" but not "should"
).
But you need correct Number_of_GPUs file in place (as with teamed pack). No teamed CPU AK_v8 apps needed, only this file.
