charset=UTF-8 Content-Transfer-Encoding: 7bit X-Mailer: WebService/1.1.26668 YMailNovation Hi Oleksij, I tested this on the affected machine with a Home Assistant OS test build that includes the patch (kernel 6.18.54-haos). Hardware: Intel NUC11ATKPE, RTL8168h/8111h (XID 541), FRITZ!Box 6690 as link partner, no VLANs. With the patch the NIC reports EEE as not supported and the RX stall is gone: more than 4 hours without a single drop, everything on defaults, no workaround. Before, on 6.18.52 without the patch, it stalled every 7-20 minutes. Since 6.18.y stable is affected (that's where the PHY EEE fix was backported), it would be great to see this there too. Tested-by: Dennis Piecha Thanks for the fix! Dennis Am Donnerstag, 1.
