[c-nsp] NPE400 12.2(28)SB breaking POS STM1

[Daniel Roesen]

Hi,

just tried to upgrade a 7206VXR NPE400 from 12.2(25)S8 to 12.2(28)SB.

Result: POS STM1 back-to-back link to a Juniper down (which worked fine
for more than a year on 12.2(25)S*:

}

Downgrading to 12.2(25)S8 makes the link work fine again.

Any known issues?


Best regards,
