https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288260 Zhenlei Huang <zlei@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |zlei@FreeBSD.org --- Comment #1 from Zhenlei Huang <zlei@FreeBSD.org> --- Thanks for your report ! Quote one from your dmesg output, > CURVNET_SET() recursion in hhook_run_socket() line 3700, prev in > ether_input_internal() > 0xfffff8000a4f7040 -> 0xfffff8000a4f7040 > KDB: stack backtrace: > db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00634c16f0 The root cause is that you have enabled `VNET_DEBUG` option in the kernel build config, KERNEL-14.2 in your case. That option is field for debugging purpose which is useful for developers. End users will barely want to enable it. The output is harmless but certainly will hurt performance in critical / fast path. To **fix** it, just disable the `VNET_DEBUG` option. Happy hacking ! -- You are receiving this mail because: You are the assignee for the bug.
