[c-nsp] 7204vxr freeze-up question

[Adam Greene]

Hmm.

Upgraded router to 12.3(23).

Even after the upgrade, passing 82.3Mbps in / 42.5Mbps out over the 
7204VXR's PA-GE interface (plus 1000BaseSX GBIC) causes the interface to 
stop passing traffic.

Reseating the GBIC does not rectify the issue. However, reseating the PA-GE 
card does.

Tried moving the PA-GE card from slot 2 to slot 3 (different PCI bus) and 
the problem still occurs.

Tried with a different PA-GE card. Problem still occurs.

I'll try with another GBIC, but that seems unlikely to resolve the issue.

It's sounding like I may need to replace this router. Ugh.

If anyone has any bright ideas, they are welcome.

Thanks,
Adam
