Ticket #18176 – Description

-              initial
+              v8
 Experiencing USB reset and hangs on Virtualbox 5.2.22 on Macbook Pro 2017 10.13.6, on Oracle Linux 7.5 and Ubuntu 18.04 VMs.  I'm able to replicate the problem, very quickly, by running the following:
+{{{
 $ sudo dd if=/dev/zero of=./testfile status=progress bs=1024k
 639631360 bytes (640 MB) copied, 5.448752 s, 117 MB/s
+}}}
 It starts out pretty fast, but once the reset occurs, the speeds taper down to < 50MB/s.  The OL system log shows the resets and I/O errors as:
+{{{

 Dec 10 15:55:38 jdnissen-lobi7 kernel: usb 2-1: reset SuperSpeed USB device number 2 using xhci_hcd
 …

 Dec 10 15:56:32 jdnissen-lobi7 kernel: JBD2: Detected IO errors while flushing file data on dm-3-8
+}}}
 I've attempted to workaround this with the new test build 6.0.0 RC1, and it didn't help.  OL and Ubuntu updates don't help, either.
