Bug#327436: kernel segv after SMB server (buffalo linkstation, running linux) was reconfigured
Package: kernel-image-2.6.8-11-amd64-k8
Version: 2.6.8-14
Severity: minor
After reconfiguration of permissions on a mounted SMB volume, the Kernel
decided to segfault (system continued to run, blocking processes that
were accessing the affected volume).
Here is what /var/log/messages had to say:
