To add a few datapoint to the 21140/21140A/21140-AC status: (the names are repeated so that the search engines will match someone of them!) the latest netbsd driver has a comment that the 21140A pass 2.0 and 2.1 have a broken receiver which might hang in case of rx overruns (this is very annoying since we have 20 of them!), which are likely to occur at 100Mbit/s with 8k NFS traffic. The driver apparently has a workaround but it is probably not operational (or, more likely, it is operational, but causes packets to be dropped; since the overrun is probably systematic, it does not allow the NFS traffic to continue; this would explain why the machine responds to pings). Now I have a machine running fully diskless with 1K NFS blocksize. pinging with 8000 bytes does not seem to cause the machine to hang. More news tonight. In the meantime, can people with problems tell me the Rev. and pass. number of their boards (printed by the kernel diagnostics) I'd really like to try and have this fixed, so your cooperation is very much appreciated.
