[Xen-users] irq issues ("nobody cared")

[Michael Kress <kress@xxxxxxxxxxx>]

Hello,

I'm having trouble during high IO activities:
Oct  8 10:38:51 matrix kernel: irq 16: nobody cared (try booting with
the "irqpoll" option)
Oct  8 10:38:51 matrix kernel:
Oct  8 10:38:51 matrix kernel: Call Trace: <IRQ>
<ffffffff801519b0>{__report_bad_irq+48}

Oct  8 10:38:51 matrix kernel:        <ffffffff8010dae4>{do_IRQ+68}

Oct  8 10:38:51 matrix kernel:

<ffffffff8011da36>{ia32_syscall+30}

<ffffffff80134587>{__do_softirq+103}

Oct  8 10:38:51 matrix kernel:        <ffffffff8011da36>{ia32_syscall+30}
Oct  8 10:38:51 matrix kernel: handlers:
Oct  8 10:38:52 matrix kernel: [<ffffffff802aa310>] (usb_hcd_irq+0x0/0x60)
Oct  8 10:38:52 matrix kernel: [<ffffffff802aa310>] (usb_hcd_irq+0x0/0x60)
Oct  8 10:38:52 matrix kernel: Disabling IRQ #16

Sometimes it's also irq 17. Of course I tried irqpoll, but no use.
Currently I'm using 'noirqbalance noirqdebug' as kernel parameters as
these two reduce the above messages, but they still occur.
Data written on disks seems to be alright, and I think, this doesn't
concern my controller, but it's strange anyways.
This doesn't arise with my distribution's stock kernel, just with xen.

My setup: Supermicro X6DH8-G2+, 3ware 9550SXU-4LP, 4GB RAM, xen-3.0.2-2
(i.e.linux-2.6.16)
Any ideas?
TIA - Michael
