5.1.6 segfault in VBoxDD.so on USB unplug

Guest type: Windows Host type: Linux

Description

Hi, the VM window just disappears. It does not happen every time. As matter of fact I was working several days now with many USB unplug events. This time I captured logs.

04:11:12.098613 VUSB: Detached '00007fe874d5be50[proxy 0c2e:096a]' from port 1
04:11:12.098710 AssertLogRel /home/vbox/vbox-5.1.6/src/VBox/VMM/VMMR3/TM.cpp(1727) int TMR3TimerDestroy(PTMTIMER): <NULL>

and syslog

Sep 15 17:14:41 don kernel: [27511.485796] USBDevIo--1[19180]: segfault at e8 ip 00007fe89133910a sp 00007fe85557ae90 error 4

Sep 15 17:14:41 don kernel: [27511.485808]  in VBoxDD.so[7fe89127a000+28e000]

I can also share the Ubuntu crash report with the devs; but do not want to see it in the public. I this also 9MB.

And I can provide the USB device if that makes a difference (I live close to Endersbach).

Here is the link to the forum post: https://forums.virtualbox.org/viewtopic.php?f=7&t=79708&p=372643#p372643 (there is also wrote about another crash, but I think the two are unrelated).

Sorry, the formatting failed somehow and some nḿinor words are at the wrong place. I guess it is understandable.

Could you provide the crash dump? Please contact me via frank _dot_ mehnert _at_ oracle _dot_ com. I cannot provide you a server for uploading, perhaps you have an URL which you can share with me in PM.
