VME trouble, new signature

At P09, starting the OmsVme58 tango server by hand generated this error message:

 
Tango exception
Severity = ERROR 
Error reason = OmsVme58 error
Desc : vme-write error, p09/motor/dif.01, base 0x1000000
Origin : OmsVme58::setup_motor_local

After removing all but the first Oms card, the error disappeared. Plugging in additional cards it was observed that certain VME slots seem to be faulty in the sense that if a card was inserted there no VME I/O was possible. At other positions the cards worked OK.

Solution: exchange VME crate.
