Description Paul Taylor 2006-08-17 17:27:20 UTC

The URL includes a patch; can this be applied to gentoo-sources prior to the release of 2.6.18?

The symptoms I'm getting are NFS suddenly stalls (very poor performance to the point that a reboot is required), and lots of these messages in /var/adm/messages:
