[ODROID XU4][Kernel 4.9.x] USB 3.0 unstable under heavy load

Postby tpoechtrager » Wed Jan 03, 2018 1:10 am

There is an issue in the 4.9.x kernel which seems to crash USB 3.0 when external drives are under very heavy loads. In my case I used a USB 3.0 Stick which delivers up to 245 MB/s.

If I executed

$this->bbcode_second_pass_code('', 'dd if=/dev/sda of=/dev/null bs=1MB ')

and had high utlizitation on the network the drive crashed with

$this->bbcode_second_pass_code('', 'reset SuperSpeed USB device number [...]')

which did not always recover successfully. This seems to be fixed in 4.14.x - at least I haven't gotten a crash until now. Another option would be 3.10, but in that version USB 3.0 is a lot slower (~220 MB/s vs. 120 MB/s).

Please upgrade the Kernel to 4.14.x. Thanks!

I am definitely not alone with this issue: https://www.google.at/search?q=%22xu4%2 ... +number%22

Upstream (https://github.com/hardkernel/linux) appears to be 4.14.13. The linux-odroid-xu3 PKGBUILD lists the maintainer as Kevin Mihelich, who is, I believe, the "all of ArchLinux-ARM" guy. Not sure he has time to keep everything up to date. Perhaps we need a separate maintainer... I might be willing to volunteer.
