Re: mmu_context_overflow

I just saw this message for the first time on one of my machines (G4/450)
as well. I've been getting a lot of 'eth0: transmit timed out, resetting'
which would freeze the network in kernel 2.2.17 (I'm now running 2.2.18,
which seems to survive it). My machine is taking on about 120,000 http
requests per hour though and there doesn't seem to be any effect on the
performance. Is this something I should worry about?

Any info would be much appreciated.

No, I don't think you should worry about these. those messages simply
need that the kernel ran out of VSIDs and had to re-assign them all. It's
perfectly harmless as long as it doesn't happen too often.

I'm more concerned about your network problems however. I beleive the
chip is a GMAC chip with a 5201 PHY (can you confirm ?). With 2.2.18, you
should not have transmit timeouts. If you have some, then there's either
a bug in the driver (which seemed to be rock-solid so far) or, we are
hitting a HW issue.

Does the gmac driver display some version informations when the kernel boots ?
