Description Alexey Dobriyan 2009-11-24 16:07:24 UTC 
Setup: 2 x nv84 (SLI theoretically), nouveau binds to both devices fine
using just framebuffer console with KMS, no X, no nothing
after echo mem >/sys/power/state suspend hard hangs somewhere after
nouveau 0000:0a:00.0: PCI INTA disabled
at this points nothing works but hard poweroff

However! if I unbind driver from first non-used card with:
echo 1 >/sys/bus/pci/devices/0000:09:00.0/remove
before suspend, then suspend and resume work just fine.

so far experimentation showed that
a) removing uhci_hcd module which shares interrupt with non-used card doesn't
help at all

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
