[OpenAFS-devel] repeatable ksymoops running cvs2cl on AFS repository

[Sam Hartman]

Shortly after running cvs2cl (or possibly during; at least once during
but I'm not sure about the most current time), I get an oops of the
following form.  My kernel and system is kind of crufty (2.4.0) but
I'm running Debian openafs 1.1.0.r There are no patches in the Debian
diff that currently get pulled into code that the AFS module uses.



I'll probably try upgrading to a more recent 2.4.x kernel.
