Kernel Panic Inside vboxsf guest kernel module => Fixed in SVN

[Matthew Pare]

I'm experiencing a kernel crash from inside the vboxsf guest kernel module when I attempt to shutdown or restart the guest os. I can make this problem not occur by not loading the vboxguest, vboxsf or vboxvideo kernel modules.

I'm running VirtualBox VM 4.2.4 r81684 on darwin.x86 (OS X 10.6.8). Results of guest uname -a are below.

uname -a Linux arch1 3.6.9-1-ARCH #1 SMP PREEMPT Tue Dec 4 09:31:43 CET 2012 i686 GNU/Linux

I've attached a screen shot of crash, cat /proc/cpuinfo, vBox.log, vboxsf.ko.

Can you reproduce the crash with

mount.vboxsf -o remount <sharename> <mountpoint>

? If so, can you attach the output of

strace -f -o foo.log -s128 mount.vboxsf -o remount <sharename> <mountpoint>

? Thank you!

I was not able to recreate the crash using

# mount.vboxsf -o remount <sharename> <mountpoint>

[Frank Mehnert]

Thanks. I think we found the problem. This should be fixed in the next maintenance release.

[Frank Mehnert]

Fix is part of VBox 4.2.6.

Thank you for your work. This appears to have resolved my issue.
