Summary: nv84 (GeForce 8600GT M) doesn't suspend with 2 cards but
with 1
Product: xorg
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: [email protected]
ReportedBy: [email protected]
QAContact: [email protected]
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
