[OpenAFS-devel] Re: OpenAFS 1.4.7pre1 Oops

[Harald Barth]

Oops on load of kernel module. I need dinner first and don'k know if I
can think about it more this evening, but for pondering, I have...
x86_64 with kernel 2.6.19.1 (almost stock). This kernel has been running
well with 1.4.2 and newer OpenAFS.

Anything I should look up before reboot?

Harald.
