SamyGO

I successfully used rooted shell, but insmod fails on nfs/cifs modules from extension pack (tried on all three versions).
As far as i understand stderr doesn't captured and i got no messages. kernel log also provides no ideas why it fails.

1) Should i build nfs/cifs for this specific kernel/platform or ones in samygo extensions should be compatible? Is there any required dependencies from other modules?
2) Can i somehow diagnose insmod errors?

have you checked maybe all modules are loaded with tv start? check samygo init scripts, cifs is enabled by default, nfs you need to enable manually (rename by removing .dis from the end)
