Sure thing. Also, feel free to let me know if you'd like access to one of the systems we saw breaking with this patch - I'm fairly sure I've got one of them locally at my apartment and don't mind setting up AMT/KVM/SSH On Tue, 2020-07-21 at 15:22 +0300, Mika Westerberg wrote:> Hi, > > [Sorry for the delay, I was on vacation] > > On Fri, Jul 17, 2020 at 01:32:10PM +0200, Karol Herbst wrote: > > Filed at https://bugzilla.kernel.org/show_bug.cgi?id=208597 > > Thanks for reporting. > > I'll check your logs and try to figure if there is something we can do > to make both nouveau and TBT working at the same time. > > > oddly enough I wasn't able to reproduce it on my XPS 9560, will ping > > once something breaks.-- Cheers, Lyude Paul (she/her) Software Engineer at Red Hat

I attached a test patch to the bug report: https://bugzilla.kernel.org/show_bug.cgi?id=208597 that tries to work it around (based on the ->pm_cap == 0). I wonder if anyone would have time to try it out.
