I don't really see anything between v5.0..v5.1 which would account for this. Could have been a subtle change to the i2c logic somewhere.

There are many guides for this online._______________________________________________On Sat, Jun 15, 2019 at 12:17 PM Mar Mel <marmel6942@xxxxxxxxx> wrote:_______________________________________________Unfortunately, even with this change now reverted in kernel 5.1.10, the fan speed issue persists.If someone could point me in the direction of a relevant commit(s) I'll happily file a bug report.On Thursday, June 13, 2019, 11:19:25 AM EDT, Mar Mel <marmel6942@xxxxxxxxx> wrote:As of kernel 5.1.9, on resume from suspend, my NV50 fan runs at full speed.Not sure if it has to do with this new config option (NOUVEAU_LEGACY_CTX_SUPPORT)?This issue is not present using kernel 5.0.21.Years ago I filed a similar issue:Thanks.
