[vbox-dev] Network adapter issue with x86_64 host/Win95 guest

[Larry Finger]

I am running the latest svn revision (2342) on an x86_64 host (openSUSE 10.2, kernel 2.6.21-rc7) 
with Windows 95 as the guest. Everything is normal if I boot the guest with the network interface 
disabled, or if the guest is in safe mode; however, if the network adapter is enabled in any mode, 
the guest aborts with the following message to the host log in /var/log/messages:

VirtualBox[27127] trap divide error rip:2aaaacc703a0 rsp:42f37f10 error:0

I will try to search around in the code for the reason, but would appreciate any tips on how to 
trace the problem and where to look.

The last few messages in the guest's log are:

I have not installed any guest additions.
