So after chasing this thing since SRC, and having gone through all the various rebuilds until now, I'm not proud to say that the evil BFD + watchdog nmi timeout bug persists.
It wasn't but just a day ago that an NPE-G1 we upgraded to SRC5, and on which we enabled BFD in the hopes that that bug had finally been found and fixed (TAC confirmed it is fixed in SRC5 - like it was in SRC1 to SRC4 - as well as other IOS branches sharing this platform-independent code), experienced an uncommanded reboot citing a watchdog timeout. Just like before. Oh well, no BFD on those, then. And something tells me even by SRC10 (should the code base last that long), Cisco will not have found a solution for it. What quality networking, we have these days... Mark.
