No, the io_page_fault is caused by the not correct alias setting so that
the scsi storage controller like 0f:04.0/0a:0a.0 can't be handled
correclty. You can see that their alias are 0f:00.0 and 09:00.0 which
are reported in io_page_fualt.

But the other 2 disks still didn't come up, I suspect if the irq is not
set right. This should be another different issue, no any idea yet.
