Bug#642409: linux-2.6: "suspend" from gnome shutdown fails when krb5/nfs4 user logged in
Package: linux-2.6
Severity: normal
On different machines (Dell Optiplex GX270, GX280, 390) with different
versions of the Kernel (x86 2.6.35, amd64 3.0.0) suspend from the kernel
fails if a user who's home directory is on a krb5/nfs4 server.
The kernel seems to be unable to freeze user tasks doing nfs ops.
Here's a bit of syslog that looks relevant:
