Title:
Bad performance of Ethernet on USB3 port, dmesg flooded with errors
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Hello,
# Summary
Plugging on USB3 port an USB-to-ethernet device yields slow performance, dmesg flooded with errors.
Plugging on USB2 port, exact same situation otherwise, works well.
Reproducible : not always, about 3 out of 4 attempts.
# Details
Observed on Asus n55s laptop with 64-bit Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz and 64-bit kernel 3.11.0-15-generic #23-Ubuntu.
Machine has 2 USB3 ports on the left, 2 USB2 ports on the right.
Device USB ID is ID 0b95:1790 ASIX Electronics Corp.
### 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" ).
