Kernal panic / core dump with ebtables + IMQ

Hi,

I tried to build a Linux bridge with QoS by using ebtables + IMQ, but 
failed. The following configurations were tried but the machine, at 
best, could only work a minutes or two then halted due to kernel panic :-

Config #1
=========
CentOS 3.8 (Kernel 2.4.21)
+ manual patching  ebtables-brnf-10_vs_2.4.21.diff.gz
+ linux-2.4.28-imq2.diff
Result : working for one minute or two, then kernel core dump

Config #2
=========
SLES8 SP2 (Kernel 2.4.21)
+ clean patching ebtables-brnf-10_vs_2.4.21.diff.gz
+ linux-2.4.28-imq2.diff
Result : working for one minute or two, then machine hang

Config #3
=========
CentOS 4.4 (Kernel 2.6.9)
+ linux-2.6.9-imq1.diff
Result : kernel panic after turning on IMQ

I hope someone could advise if there is no hope to make it work for 
ebtables + IMQ, or there was something I missed.

Thanks a lot.

John Mok
