Summary: 2.6.26 (sata_nv = irq 21 problem after halting)
Product: IO/Storage
Version: 2.5
KernelVersion: 2.6.26
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Serial ATA
AssignedTo: [email protected]
ReportedBy: [email protected]

Latest working kernel version: 2.6.25 Earliest failing kernel version: 2.6.26
Distribution: Linux from scratch
Hardware Environment: athlon64 x2 5600+, Asus M2N-E Software Environment:
Problem Description:

Something happened with ncq's sata_nv support. When I halt my
system (Athlon64, Asus M2N-E), I get the following (I had to copy by hand, since the system is halted, so it's just an excerpt):

IRQ 21: nobody cared (try booting with the "irqpool" option) Pid 0, comm: swapper not tainted 2.6.26 #2

Call trace:

........... nv_swncq_interrupt
........... __report_bad_irq
........... note_interrupt
........... handle_fasteoi_irq
........... do_irq
........... ret_from_intr

Handles:

[<f88888888803a5b90>] (nv_swncq_interrupt+0x0/0xd0)

Disabling IRQ #21

This just happens after a halt.

If I use irqpool, this error doesn't happen.

Thanks.

Steps to reproduce:

Just shutdown the system (halt).

It's a 2.6.26 regression. It happens at halt-time, so it won't be the usual ACPI stuff.

I think this is the second report of ata going splat in this manner at shutdown time. Did we get the order of something wrong?
