Hi All,

Many thanks for your nice responses.

I bisected today [1]. 0412841812265734c306ba5ef8088bcb64d5d3bd (of/irq: 
Allow matching of an interrupt-map local to an interrupt controller) [2] 
is the first bad commit.

I was able to revert the first bad commit [1]. After a new compiling, 
the kernel detects all ATA disks without any problems.

I created a patch for an easy reverting the bad commit [1]. With this 
patch we can do further our kernel tests.

Could you please check the first bad commit [2]?

Thanks,
Christian
