SVI's not passing traffic.

I have a Cisco ISR with a switch module connecting via 802.1Q trunk to a 2960-X switch stack. There is an SVI on the ISR for each of the vlans on the switch. We recently reloaded the stack (non upgrade) and when the stack came back up, 4 of the 10 vlans were no longer able to even ping the GW on the SVI while all of the others on the trunk were fine. To fix it, I ended up deleting the SVI and the vlan and recreating them to get it to work. J/W if anyone else has seen this before and knows what may cause it?

​

I Did verify first that the vlans and the SVI were up up.

deleting just the SVI on the ISR didn't work.

​

thanks!
