Comment 87 for bug 1729674

I seem to be seeing this again with the following kernel:
Linux xps15 5.0.0-17-generic #18-Ubuntu SMP Tue Jun 4 15:34:08 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

The problem is not so much checksum errors, but mostly that transfers are abruptly aborted. I also see this in my syslog:
