SubjectOops in i2o_block in 2.6.0 and 2.6.1 with Promise Supertrak 100
Hi I have been trying to use the i2o_block in order to use my Supertrak
100.  In both 2.6.0 and 2.6.1 it oopses.  However in 2.4.22 and preceeding
versions it works flawlessly.  I am using 1.00 Build 13 flash version of
the controller, however I was previously using 1.00 Build 11 with the same
problem.  I have attached the Oops and the kernel config.  If anything
else is needed just let me know.

Cheers
Darrell Wright
