Its spewing events we didnt ask for then it dies

That says it all. Thats a message from the controller on the SX6000
saying "I broke".

You will need at list 2.4.19ac from a cold boot for this card to work.
Also check your boot logs to ensure it skipped over the PDC20276
controllers correctly. I think the code is right but I am not yet sure.

If we don't skip the 20276 chips properly then we reconfigure them and
the raid card has kittens (rightly so)

Its an invalid I2O event code. Promise cards emit them before crashing
when you ask them to do anything they take offence too.

Actually the promise provided driver for the supertrak cards seems to
work fine. I actually used it to debug the generic i2o_block support for
their chips. It won't help if we are eating the ide controllers however
