Bugs #6109, #4722 and #6340 have been marked as duplicate of this one.

Let me know if you want to try out a build with a possible fix.

[sammy2ooo]

i would like to test a possible fix. could you please attach it? btw: i am the OP of bug id 6109

[sandervl73]

I can only provide you with a .run Linux installer, which might not be what you want. Windows builds are much easier. :)

[sammy2ooo]

i am on Fedora x68_64 linux so a .run binary would be fine. could you please also have a look at  http://www.virtualbox.org/ticket/6109

[sandervl73]

You can try the following build:  http://www.virtualbox.org/download/testcase/VirtualBox-2010-03-10-14-27-59-lin64-3.1-3.1.5-r58636.run

sammy2ooo: can you always reproduce this guru meditation? If so, is it possible to get access to your VDI?

[sammy2ooo]

What do you mean by VDI? No indeed, I can not reproduce this crash at every boot.

(OT: how is the meaning "guru meditation" tight to a crash???)

[sammy2ooo]

However, booting Windows 7 in "Safe Mode" always seems to work...

[sammy2ooo]

I started the virtual machine from CLI using "VBoxManage startvm "Windows 7" -type vrdp" and then connected via MS Remote Desktop Client

[frank]

With VDI he meant the virtual disk image of your VM. For the term guru meditation see  here.

[sammy2ooo]

sandervl73: i could give you access to a copy of my vdi file, as it is a somewhat freshly windows 7 install. do you have any ftp account for me where i could upload the file?

[sammy2ooo]

the vdi is about 5.9G long (bziped)

[sandervl73]

So you always start this VM with the option -vrdp and connect with the MS RDP client when you see this guru meditation? I haven't tried that here yet. Also please give me an indication as to how often you can reproduce this problem? (every time, 1 out of 2, 2 out of 5 times?)

[sammy2ooo]

no i do not start the vm all the time with the vrdp option, sometimes i use the virtualbox gui with the exact same result. this crash seems to occur randomly while booting. i would say about 1 out of 5 boot attemps are successful

[sandervl73]

Ok, please upload the file to  ftp://ftp.virtualbox.org/incoming (write only; others can't see your file). Thanks!

[sammy2ooo]

thanks for your space. upload is in process and may take up to a few hours...

[sammy2ooo]

I have finished the upload, i hope we dont have any CRC's... please also have a look at the sha1sum file and let me know if everything went fine

[sandervl73]

Thanks. Downloading. If I can't reproduce it, I'll post a link to a new build here as I've fixed something possibly related yesterday.

[sammy2ooo]

hm i have recognized when trying to adding this vdi to a VirtualBox Installation which runs on Windows XP Host (Version 3.1.4) I receive this error message. Maybe my vdi is (or got while sending over network) simply corrupted?

[sandervl73]

Not sure, but tar doesn't like the extracted tar file here (bzip2 didn't complain though). A new test build can be downloaded here:  http://www.virtualbox.org/download/testcase/VirtualBox-2010-03-17-14-24-02-lin64-3.1-3.1.5-r58927.run

Could you give that one a try?

[sammy2ooo]

Thanks for that build. Unfortunately the same problem occurs...

[sandervl73]

We managed to extract the tar file. My tar binary is perhaps a bit outdated. Will give your vdi a try.

[sandervl73]

Your VDI is fine, but unfortunately I'm not able to reproduce your problem here.

[sandervl73]

Funny, tried again and I got it. :)

[sammy2ooo]

Yes, this is really odd. nd I guess pretty hard to hunt down or find out what is causing it.... I hate randomly occuring erros X-)

Any ideas or insights?

[sandervl73]

Already found and fixed. I'll post a link to a test build tomorrow if no regressions show up overnight. Thanks for your help.

[sandervl73]

Should be fixed now. Could you try:  http://www.virtualbox.org/download/testcase/VirtualBox-2010-03-19-13-43-56-lin64-3.1-3.1.5-r59035.run ?

[sammy2ooo]

YES!!! This really seems to have fixed it, tested it several times....What was causing this issue? Will this fix be included within the next stable release?

[sammy2ooo]

one more question: is this the opensource version? usb is not working anymore and greyedout

[sandervl73]

It's not the opensource version, so usb should work. 3.1.6 will be released soon and will include the fix.
