Hi Bjorn

no we aren't deadlocked :-). I didn't get around changing it to ordered
queue yet, mostly worried about having to retest all the different 
combinations with ATTN, POWER_CTL, SLD.

I'm depending on other folks to test SLD. They are tied up with other
issues ATM.

I have had another OEM test with several disks and multiple ATTN's 
pressed/cancel and current code seems to be working well so far, except the 
SLD case.

The change in the patch was only ensuring that we don't start another 
POWER_ON or POWER_OFF before the earlier operation was complete.

Would it be alright to fix SLD with this version while we can probe a clean
approach that can give us sufficient time to test a clean approach that works
with all the different combinations and OEM systems?

Cheers
Ashok
