[Xen-users] Segfaults in dual nics

[Brett Stevens <brett@xxxxxxxxxxxxxxxx>]

Hi, sorry in advance if this question has been asked before, however  
I can't seem to find a solution to this
The problem is a segfault in what looks like the nic driver  during  
boot. This segfault can be recreated with a rcnetwork restart
dmesg is

testparm[3625]: segfault at fffffffffffffff8 rip 0000555555581592 rsp  
00007fff730615c0 error 4
testparm[3856]: segfault at fffffffffffffff8 rip 0000555555581592 rsp  
00007fff0bef34e0 error 4
this occurs only in multi nic domu's however once this occurs Im  
stuck with it. Even if I remove references to the second nic in
the domu config and remove all references to it in the domu it self  
such as udev sysconfig etc
the system also has a total of 4 nics two physical and two dummy
the problem occurs reguardless of the type of second nic


the weird thing is the nics seem to work ok except on shutdown of the  
domu when some network services will fail to unload properly such as  
autofs and ldap

Details are as follows
