I have an Atom-based machine (N450) with an ICH8 running Ubuntu LTS

I put the machine into S3, then woke it from the network. After
resume, the uhci_hcd and ehci_hcd devices (sharing an interrupt)
start flooding interrupts. This continues until the USB driver is
reloaded, or I reboot.
Is this a known issue? I'm willing to assist debugging, I just
wanted to ask if people have seen this yet before I dig into it. If
it comes down to building linux-next via git, that's fine, it'll
just take about 4 hours on this box to do it.
Let me know if there's any additional data folks want to see.
Can you see if this happens with the latest 3.8.3 kernel release? If
you are stuck using Ubuntu kernels, you need to get support from
Canonical, there's nothing we can do with their kernel packages, sorry.
I cannot reproduce this problem with 3.8.3 on the same box. I'll open a
bug with Canonical.
Sorry for the noise, but thanks for the quick reply nonetheless.
Cheers,
