The files I am reading are read over NFS,
Ah, thanks for the description.
2.6 has a problem with NFS filesystems that would cause symptoms like yours. I'm not sure whether 2.4 has something similar or not. You can probably expect a fix for 2.6.6 but I'm not sure if there is a patch that has been agreed upon yet.
In short, there probably isn't much point testing 2.6 right now. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
