--- Comment #3 from Ilia Mirkin <[email protected]> --- (In reply to Marcin Zajaczkowski from comment #2) > Hello again. I upgraded my system to Fedora 21 and with > 3.17.3-300.fc21.x86_64 I cannot reproduce mentioned issue (with "CPU#0 stuck > for 22s"). > > Unfortunately I have problem with switching a discrete card. By default: > # echo OFF > /sys/kernel/debug/vgaswitcheroo/switch > does nothing - a discrete card is still in DynPwr state: That's expected. What's unexpected is that something is keeping a reference to your GPU which isn't letting it power off. Similar to bug #70875. > Booting with nouveau.runpm=0 I have both cards on: > $ $ sudo cat /sys/kernel/debug/vgaswitcheroo/switch > 0:IGD:+:Pwr:0000:00:02.0 > 1:DIS: :Pwr:0000:01:00.0 > > and after > # echo OFF > /sys/kernel/debug/vgaswitcheroo/switch > > I have: > 0:IGD:+:Pwr:0000:00:02.0 > 1:DIS: :Off:0000:01:00.0 > > Looks ok, but I still see 3 providers: > $ xrandr --listproviders > Providers: number : 3 > Provider 0: id: 0x90 cap: 0xb, Source Output, Sink Output, Sink Offload > crtcs: 3 outputs: 5 associated providers: 2 name:Intel > Provider 1: id: 0x63 cap: 0x7, Source Output, Sink Output, Source Offload > crtcs: 2 outputs: 2 associated providers: 2 name:nouveau > Provider 2: id: 0x63 cap: 0x7, Source Output, Sink Output, Source Offload > crtcs: 2 outputs: 2 associated providers: 2 name:nouveau > > and system temperature could suggest that the card is still on. I see no > messages from VGA switcheroo in the system log (as there were in 3.11.6). That is odd... not sure what that situation is. > Should I close that issue and report another issue? Yes, don't confuse multiple issues into one, it gets unwieldy. -- You are receiving this mail because: You are the assignee for the bug.
