Subject: 3.2.x Regression for SAS Controller on Dell C6100


Greetings!

I'm seeing a regression on a Dell C6100 machine with
3.2.x kernels, where the second disk (in a raid setup)
is not properly recogniced and so the raid drops into
degraded mode

the same hardware works fine with 3.1.x kernels and
older

attached the dmesg output of the bootup for a working
and a failing kernel

thanks in advance,
Herbert
