8212 running K.14.60 crashing

[TonySweet]

We recently upgraded the 2nd of our core switches to version K.14.60, the 1st being updated 2 months ago. 3 days after the upgrade the switch crashed several times and the only way we were able to stablise the switch was to remove MM2. We think we may have a dodgy MM but has anyone else experienced crashes on K.14.60? We've checked our logs but there was no crash info saved or clue as to teh underlying cause.

Hi Tony

Would you mind posting the output of "show boot-history"

We have 24 devices running K.14.60 at
our site (5400zl's and 3500yl's), and
no issues to date. 7 of those are
running routing/ospf, the other 17
are layer 2 only.

We haven't upgraded our five 8212zl's
to K.14.60 yet.

Hi Tony

It is really hard to diagnose the downed module. Do you have a spare chassis you can test it on ?

We don't have a spare chassis but we do have a spare module which we are looking to install. I suspect it is a hardware problem as we have another 8212 running K.16.30 without any issues.
