[ManU]

Host: ArchLinux Guest: Gentoo

[Frank Mehnert]

Which is the last VBox 4 version you tried?

[ManU]

4.0.4 it is still a regression bug, since in 3.2.12 it worked!

[Frank Mehnert]

To me it looks like some special kernel config setting. Please could you attach your kernel configuration? 2.6.37 works very well here...

[ManU]

frank with this kernel vbox 3.2.12 runs without problems (compiled against this kernel), this bug exists since 4.0. with the latest windows release it does work also.

i think its a regression-bug in the linux fork... how to paste the config settings? i dont compile kernels by myself

[ManU]

I tested it under Windows as host, there all works fine with: vbox 4.0.4r7xxx

so its only a regression in the linux fork since 4.0.0

[Frank Mehnert]

Can you attach a VBox.log file from a VM session where this crash happens? Regarding the kernel config, I don't know where Gentoo stores the kernel config but it is normally the file .config in the root directory of the Linux tree.

[ManU]

Crashes also with kernel 2.6.38, here is the log:

​http://pastie.org/1787849

[ManU]

does the log help?

[ManU]

Also crashing with 4.06 r71344 ​http://pastie.org/1821956

but sicne 4.0.4 the bug changed from a total crash of vboxdrv to this strnge mouse pointer bug, but the result is the same, i need to kill the virtual machine process.

under windows it does work and also with other hosts. it also does not work with any mac osx guest if that helps...

[ManU]

Also crashing with 4.08 r71778 The module doesnt crash anymore, but the whole VM-windows freezes

[ManU]

before freezing the window flickers fast between black and the graphical Xserver of the vm

[ManU]

also happens with release 4.1.2

the module crashes and the window freezes

[ManU]

kernelog and vboxlog

[Frank Mehnert]

Please attach the complete VBox.log file of this session to this ticket. Do NOT paste the content!

[Frank Mehnert]

This could be also related to #7390 so if your guest uses PAE, try to disable it.
