2.6.0-test5-mm4 Oops

[Eric Balsa]

Hello,

  I am seeing a kernel oops when booting 2.6.0-test5-mm4. Below is the oops.
Looks like it is from the ACARD driver, since when I disable it in the
kernel, the oops no longer happens. This is a dual Xeon 866 (Dell Poweredge
4400) with an SMP kernel. I hope the ksymoops is useful.

Regards,
--Eric
