Is it the problem with stacking enabled on hp2910 switches?

1. Looks like you run rancid command as root. Don't! You will end up 
with files not owned by your ranciduser and get more trouble.

2. If you are running as rancid-user I thing you get correct path 
settings to find hpuifiler. hpuifiler and hlogin is proper installed in 
your "rancid/bin"-dir if it's work for 2650's.

3. clogin don't use hpuifiler so it will not work to with Procurve switches.

4. There is a new prompt on hp2910, if you have "stacking" enabled.
Test to turn off stacking and run hlogin/rancid-run as you do with 2650's.
If you start using ssh to login, you can find a patch for ssh login to 
2910 switch stack member 0, posted pevious on this list.
