Package: linux-source-2.6.26 Version: 2.6.26-21 Severity: normal
My main file and login server machine crashed, with an Oops in the logs. I do not know whether this crash is reproducible: it crashed also a week earlier, but with nothing visible in the logs; it had been stable for months before these two crashes.
