DAHDI not working for TDM400P

Hi forum
Installed a genuine Digium TDM400P, and Asterisk 11. Also dadhi packages.
BUT can’t get TDM400P analog card working.

Hardware is detected by lspci

dmesg | grep dahdi
dahdi: Version:
dahdi: Telephony Interface Registered on major 196
dahdi: Warning: Span WCTDM/4 didn’t specify a spantype. Please fix driver!
dahdi: disable_span: span 1
dahdi_transcode: Loaded.

Please for any advice to get this Digium card working.
Do I need some other driver/s ?

Looks like re-seating the TDM400P in the PCI slot might have solved the problem.
