System crashes when ifup/ifdown is used few times

Solution Verified - Updated -

Issue

After 2-3 ifup/ifdown commands in a VLAN and bonding network environment, system crashes in kernel panic (if you want I have a dump).

About the kernel problem I've done a crash test with non patched rt kernel (2.6.33.9-rt31.64) and the behaviour is the same, after 'ifdown' command issued a kernel panic occurs.

Environment

MRG 1.3

The MRG 1.3 kernel is in maintenance mode, and only critical issues will be addressed.
