I'm using Fedora 8, the 2.6.24.4-64.fc8 kernel and kmail 1.9.9 > on kde 3.5.9-5.fc8. The nfs fileserver runs Fedora Core 3 with the > 2.6.9-1.667 kernel (old machine).

(I just wonder if this could be due to poor time resolution, so if e.g. switching from ext3 to xfs would work around the problem.) --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
