The 'error mapping mbuf' error seems to have been fixed by the latest set of changes to if_bce.c - after upgrading to the latest stable, that problem stopped happening. However, instead of that, under rather higher load, we now get the watchdog timer error instead. This is not good :) I can get it within minutes with something like building something big from ports, during the initial source download. > However, the fact that I do get the error every now and then is still a > concern, so I plan to rebuild world and kernel when I get the chance. > > Please keep us posted on your findings, and if it'd be useful to have > another box to run tests on, I'd be happy to give it a go. I think moving to stable will fix the mbuf error for you, as that's what others report. You, and all the other reports I've seen have been running amd64, which I haven't been (I didn't build the box originally). I'll know tommorow if amd64 makes much of a difference or not. Oh, other info - I'm running the standard SMP kernel config with no modifications. Sam. -- "Fortified with Essential Bitterness and Sarcasm" Matt Groening, "Binky's Guide to Love".
