[vbox-dev] [PATCH] VirtualBox on FreeBSD

[Alexander Eichner]

Hi Shin-ichi,

thanks a lot for the patch. This should explain the crashes when
unloading the kernel module.
I'll apply it shortly. I also forwarded the mail to our vbox developers
mailing list. You should send patches there instead of mailing them to
me privately so that everyone can see and test the patch.
Thanks again!

Kind regards,
Alexander Eichner
