Hi
A host does not go down.
I also tried it with `irqpoll` with the same result.
Remaining filesystems read-only ...

irq 18: nobody cared (try booting with the "irqpoll" option)

Normally I'd assume that this is an acpi-caused problem with IRQ
assignments. But given that it happens only at machine shutdown time, it
is more likely to be an ordering-of-operations bug in the ata code?

Alexander, is this a regression? Was 2.6.25 OK?
Thanks.

Yes, it is a regression, 2.6.25 worked better.
