Subject: Kernel 3.7.[12] - irq 16: nobody cared
Hi all,
Firstly, please include me in any replies as I am not a list subscriber.
I'm trying to nail down a problem using Xen 4.2.1 & Kernel 3.7.1 (also
3.7.2). It seems at random periods of time I get the following via the
syslog:
Message from syslogd@...host at Jan 15 09:02:36 ...
kernel:Disabling IRQ #16
Looking at IRQ16:
[root@...host xen]# cat /proc/interrupts | grep 16
16: 1900000 xen-pirq-ioapic-level sata_mv
I also see this in the dmesg:
irq 16: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #16
I have tried booting with the irqpoll option on the kernel boot line,
but the same problem occurs.
It seems disk throughput almost drops dead when this happens - as the
SATA controller seems to go into some different mode of operation. It
also seems like this has only happened recently - I was using builds of
3.6.x as my Xen Dom0 kernel with no signs of this problem.
Has anyone else seen this in recent kernel releases? I'm not quite sure
how to try and track this down.
