Alexander reported in <http://bugs.debian.org/632187> that the kernel
took a very long time to boot, and the log showed first i2o_core and
then megaraid failing to probe a device (ID 101e:1960).  But above he
reports that megaraid is able to probe it successfully if i2o_core
didn't break it first.

Should this device be blacklisted from i2o_core?  Are there likely other
MegaRAID devices that use the I2O PCI class but don't work with this
generic driver?

Ben.
