Trouble installing NextDNS to Bazzite
if tailscale doesn't help you in other ways I wouldn't bother ;-).

Trouble installing NextDNS to Bazzite
This is a little bit of an alternate way of solving the problem: If you are using tailscale (supported by bazzite by default). You can just setup nextdns inside of tailscale instead (which has all sorts of other benefits if you are doing other things with ts). Then you don't need to change anything on your pc at all (just in the tailscale console). https://tailscale.com/kb/1218/nextdns

ok now trying a (probably really bad for sleep power consumption) test of just not letting the usb host controller enter d3cold state while linux is asleep. So then (since still in d0 state at wake, the usb init code should skip trying to stop its endpoint)

alas - that wasn't the problem. after 45 sleep cycles it finally failed with the usual xHCI host not responding...

also: without this quirk something was clearly stalling on the way into sleep also. Because sleep entry is now much faster.

hi @antheas - I spent a bit of time browsing through the xhci code in particular the areas related to 'host controller didnt talk to us after waking from sleep'. Then I saw an existing quirk (XHCI_SUSPEND_RESUME_CLKS) that seems relevant.
So I turned on XHCI_SUSPEND_RESUME_CLKS via the kernel command line and after >20 manual sleep/wake cycles I still haven't seen a failure. Caveats: * I still need to leave a good stress test running overnight. Do you know if there is any standard tooling in desktop linux land for "do 100 sleep wake cycles"? otherwise I'll have to figure out how to write a suitable script. * I haven't yet checked the power-consumtpion implications of calling clk_disable_unprepare() on the way into sleep. I'll update once I know more, but if it works the temporary fix might be just to add a karg for flow. If you want to play with this the karge is xhci_hcd.quirks=0x080200000010 (the other flags were all set by default if booted with kargs=0.

i'm currently using aurora-dx (and longer term i'll probably stay with that) - kernel 6.14.3. if you want I can try a quick reboot into bazzite-testing to see if I see the same thing. does your cpu lockup on wake from sleep?

interesting! I only have that xhci blows chunks and stops talking (and I have to reboot because then all usb devices are inaccessible) problem - but it is rare for me

Only the rare usb host controller going away bug I alluded to previously. 1 in 20 wakes?

btw 6.14.4 might remove the need for the 0x410 debug flags that I needed: commit 56daad28d6c6e1157ad9021d3dab50e733f22f58 Author: Tom Chung <[email protected]> Date: Wed Mar 19 16:31:31 2025 +0800 drm/amd/display: Do not enable Replay and PSR while VRR is on in amdgpu_dm_commit_planes()
commit 69a46ce1f15b4391c128d581f6936750f9bfa052 upstream.
[Why] Replay and PSR will cause some video corruption while VRR is enabled.

yep - the fix is in there! though strangely I still see this exact failure (that this fix was supposedly to address) occur (rarely)
