The kernel is currently compiled with PARANOID_KERNEL_FREE
by default, so the changes in hrev43046 actually affect the kernel. Apparently, the network stack does not like memory initialized with 0xcc somewhere affecting tcpdump.

yep, compiling with KERNEL_DEBUG_LEVEL 0 "fixes" this issue and tcpdump works in such build.
