Thanks for the suggestion, but I don't think it applies here. I'm using the default (-n 4), but this is the only mount from localhost, so that should be sufficient. Besides, the same problem occurs when trying to mount from a NetApp filer. Also, I don't have "erratic come & go problems", but the mount(8) command simply hangs right from the start. I'm not using amd, if that matters (I don't think it does). Since I weren't able to track this problem down, I now tend to think that it's a bug in the NIC (either broken hardware or a bug in the bge(4) driver) that makes it break TCP NFS packets somehow. I don't have any other explanation. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
