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?

I²O will probe I²O class devices. How well it works depends upon the
firmware version of the specific board.

The fix in this case is either updated firmware, or to go into the
configuration for the board and turn off I2O support in the bios config.
