Hello, I compiled a kernel last night and when rebooted it on an SMP 
machine, I got a panic when it initialized the bridge0 virtual 
interface, photos of it and the output of trace are available at [1] 
(core dumps are in the kernel directory). Reverting to the GENERIC 
kernel seems to fix it.


P. S.: my kernel config has the following extra options compared to GENERIC:


# Bridging support
pseudo-device bridge
pseudo-device vlan
device pf
device pflog
device pfsync
options         ALTQ            #alternate queueing
options         ALTQ_CBQ        #class based queueing
options         ALTQ_RED        #random early detection
options         ALTQ_RIO        #triple red for diffserv (needs RED)
options         ALTQ_HFSC       #hierarchical fair service curve
options         ALTQ_PRIQ       #priority queue
options         ALTQ_NOPCC      #don't use processor cycle counter
options         ALTQ_DEBUG      #for debugging
# Symmetric Multiprocessing support
options        SMP                     # Symmetric MultiProcessor Kernel
options        APIC_IO                 # Symmetric (APIC) I/O

Any ideas?

Thanks in advance.
