Bug#754420: linux-image-3.2.0-4-kirkwood: Kernel oops (NULL pointer dereference) under high NFS load
Package: src:linux
Version: 3.2.60-1+deb7u1
Severity: normal
Dear Maintainer,
the kernel of my NAS recently began to oops while I am building a large
source package (see syslog excerpt below). dpkg-source runs on a client,
the files are stored on filesystem exported by the NAS with NFS4.
This happend three times after the latest kernel update, but never
before.
