Hi mlx, >From the calltrace, it looks like the transmit doesn't work when problem happens, it is probably a problem of the driver lan78xx.c or a problem of the usb host driver.
So when problem happens, does the other usb ports still work? and the latest kernel -1019 version integrated a couple of patches to lan78xx.c, you could do a test with -1019 kernel. And looks like other people also met the similar problem (at least similar calltrace): https://www.raspberrypi.org/forums/search.php?keywords=lan78xx+transmit+queue+0+timed+out&sid=54addf297812dfe931b66a621bcae444 And I am still trying to reproduce this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861936 Title: Raspberry Pi 3 network dies shortly after a burst of SD card IO and network load ((lan78xx): transmit queue 0 timed out) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1861936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
