[Linux-ia64] Lost clock tick on CPU 0 (now=3b6bca57923, next=3b6b627b32c)!!

Hi,

I am getting regular messages like the one above on my Lion system. I
appears to me that these messages are in relation to other errors I am
getting like hanging processes NFS IO errors etc.

Can any one comment on this?

On your Lion are you using the builtin eepro 100 controller ? We have 
seen things like that with that flaky controller. Ever since we added
an extra eepro100 PCI card in the machine I don't recall ever seeing this
again.

Thanks for the info!  We've been getting that on our systems too.  We
haven't seen any other network-related issues, but we haven't pushed
that too much.

Adding an extra eepro and disabling the onboard one did not help.
