Package: linux-image-5.6.14 Version: 5.6.14 Severity: important Dear Maintainer,
* What led up to the situation? Noticed that the sky2 ethernet driver was flooding /var/log/messages like so: Jul 18 15:03:06 nehalem kernel: [75100.182612] device eth0 entered promiscuous mode Jul 18 15:03:08 nehalem kernel: [75102.108331] device eth0 left promiscuous mode Jul 18 15:03:11 nehalem kernel: [75105.182616] device eth0 entered promiscuous mode Jul 18 15:03:13 nehalem kernel: [75107.175461] device eth0 left promiscuous mode Jul 18 15:03:16 nehalem kernel: [75110.222602] device eth0 entered promiscuous mode Jul 18 15:03:18 nehalem kernel: [75112.181979] device eth0 left promiscuous mode This will ping-pong forever without corrective action. It can be stopped by enabling promiscuous mode on the interface, i.e. 'ifconfig eth0 promisc'. That however should not be necessary. By testing older kernels (and therefore older versions of the sky2 driver) I discovered that as of 4.9.2 and earlier this problem did not exist. At some point between 4.9.2 and 5.6.14 changes to the driver introduced this problem. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.6.14 (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_WARN, TAINT_OOT_MODULE Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
