vlan routing issue


Hi,
I've got an issue with integrating a further switch to a vlan infrastructure.
The situation is:

switch A and switch B with different vlans.

Switch A (192.168.123.250):
Port 1 = tagged VLAN 123 = uplink switch C (HP procurve 1910)
Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch B
vlan interface configured

Switch B (192.168.123.249):
Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch A
vlan interface configured


Switch C (192.168.123.248):
Port 24 = tagged VLAN 123,untagged VLAN 1 = uplink switch A
Port 1-10 = untagged VLAN 123
vlan interface configured

Communication between switches A and B is okay, I can ping all devices and all interfaces.
But switch C (interface) is not reachable, neither from A nor B!

IP Routing on Switch C is:
192.168.123.0 192.168.123.248
192.168.123.248 127.0.0.1

Did I forget something? Anyone who can shed some light?....

Network look like there is a loop. Is spanning tree on? The port could be shut down automatically.

I'm afraid I'm blind....the connection is:

tagged: C/Port24 ---------- A/Port1
tagged: A/Port24 ---------- B/Port24


untagged C/Port1-10
untagged A/Port2-10
untagged B/Port1-10
