Plugging on USB2 port, exact same situation otherwise, works well. This is reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. ### When working (USB2 port) * ethernet auto-negociation is fast * mii-tool is fast (typical 0.05s) * few lines in dmesg * good performance ### When failing : * ethernet auto-negociation fails, then sometimes eventually works * mii-tool is slow (10s of seconds instead of 0.05s) time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m40.014s user 0m0.013s sys 0m0.006s time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m50.015s user 0m0.011s sys 0m0.011s time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m10.051s user 0m0.000s sys 0m0.012s But on some attempts mii-tool is fast... time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m0.057s user 0m0.011s sys 0m0.012s * DHCP eventually completes (after about 30 seconds) then ethernet works. * whole system behaviour feels a little sluggish (not very clear, though) * mii-tool still slow (10s of seconds instead of 0.05s) ## dmesg when failing Full dmesg attached. Specific lines with occurrence count at random point (obtained with "dmesg | sed 's/^................//' | sort | uniq -c | sort -n" ). 50 ei_me 0000:00:16.0: reset: wrong host start response 51 ei_me 0000:00:16.0: reset: unexpected enumeration response hbm. 60 ax88179_178a 4-1:1.0 eth1: kevent 4 may have been dropped 100 ei_me 0000:00:16.0: unexpected reset: dev_state = RESETTING 141 xhci_hcd 0000:04:00.0: ERROR Transfer event TRB DMA ptr not part of current TD 214 ax88179_178a 4-1:1.0 eth1: ax88179 - Link status is: 1 Another attempt 11 ax88179_178a 4-1:1.0 eth1: Failed to read reg index 0x0000: -110 14 ax88179_178a 4-1:1.0 eth1: Failed to write reg index 0x0002: -110 61 xhci_hcd 0000:04:00.0: A Set TR Deq Ptr command is pending. 61 xhci_hcd 0000:04:00.0: WARN Cannot submit Set TR Deq Ptr 209 ax88179_178a 4-1:1.0 eth1: kevent 4 may have been dropped 809 ax88179_178a 4-1:1.0 eth1: ax88179 - Link status is: 1 925 xhci_hcd 0000:04:00.0: ERROR Transfer event TRB DMA ptr not part of current TD 5 IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready 6 ax88179_178a 4-1:1.0 eth1: Failed to read reg index 0x0001: -110 6 ax88179_178a 4-1:1.0 eth1: Failed to read reg index 0x0009: -110 6 ax88179_178a 4-1:1.0 eth1: Failed to read reg index 0x000a: -110 6 net_ratelimit: 31 callbacks suppressed 9 IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready 10 net_ratelimit: 30 callbacks suppressed 14 ax88179_178a 4-1:1.0 eth1: Failed to read reg index 0x0000: -110 14 ax88179_178a 4-1:1.0 eth1: Failed to write reg index 0x0002: -110 209 ax88179_178a 4-1:1.0 eth1: kevent 4 may have been dropped 232 xhci_hcd 0000:04:00.0: A Set TR Deq Ptr command is pending. 232 xhci_hcd 0000:04:00.0: WARN Cannot submit Set TR Deq Ptr 610 xhci_hcd 0000:04:00.0: ERROR Transfer event TRB DMA ptr not part of current TD 809 ax88179_178a 4-1:1.0 eth1: ax88179 - Link status is: 1 Jan 16 18:39:35 n55sf-l kernel: [203181.206451] xhci_hcd 0000:04:00.0: A Set TR Deq Ptr command is pending.
