Hello,
We've the following setup:
2960L connected via two uplinks as port channel to VSS & another 2960L also connected via port channel to vPC.
The issue is, suddenly the switch became unreachable, no console (stuck) but the traffic still pass-through. The port channel status from the second end became as "I - stand-alone"
After rebooting the switch, things back fine as expected.
We've tried so far to upgrade the IOS to 15.2(6)E2b / 15.2(7)E3
Any suggestions?

No I'm not able to reach it, as the switch is frozen, after rebooting it, it works normally for 3 weeks or even a month before losing the management again.
There are no routing issues, this switch is totally layer two switch with access interfaces configured for the VLANs that are passed in the trunk with the VSS.
The only IP address which is configured on the switch is interface vlan 130
172.28.130.40
with a default route / GW to 172.28.130.1 for management purpose.

some suggestions since we do not know the root cause of freezing.
1. Enable Logging to send the Logs to Syslog server
2. if this is layer2 why not configure the switch port with IP address directly instead of using SVI VLAN for VLAN 130.
interface gi x/x
no switch port
ip address 172.28.130.40 255.255.255.X
