Hi everyone, here is a bug that occurs when a RTL8153 is connected to the host via an ASM1042A chip. I wrongly submitted a report at bugzilla.kernel.org - sorry for that. RTL8153 connected via ASM1042A is used in Dell's TB15 and TB16 docks. So anyone using these docks is probably affected. To reproduce: - boot - connect to network via the docks ethernet jack - issue dmesg via ssh on a remote computer (not necessary but this reproduces the error in 9/10 times and when issuing dmesg twice it's 10/10) - get errors like "bad mac" on ssh (you may also get bad macs while browsing on a HTTPS homepage) <insert some time here (some people report that this occurs on high throughput)> - ethernet link is not usable anymore - find dmesg output below If I connect a RTL8153 to a different USB Port (not ASM1042A) everything works as expected (no wrong macs, no dmesg output). Ansis Atteka already digged into this issue. He wrote a mail about this here which may help any developer who looks into this: https://www.mail-archive.com/linux-usb@xxxxxxxxxxxxxxx/msg85071.html There are bugreports on Ubuntu and Archlinux: https://bugs.archlinux.org/task/53998 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975 Trace and dmesg from launchpad: https://launchpadlibrarian.net/312961448/4.11.dmesg.txt https://launchpadlibrarian.net/312961185/4.11.trace.txt I can still reproduce this with 4.11.4 I am able to patch the kernel and test it :) Thanks, Frederik -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
