Hmm, then thn I guess a default like dev.netmap.priv_ring_size has changed, because my em txd/rxd were default 4096, for both, native stable/11-netmap and HEAD-netmap... Reducing r/txd to 1024 solved the problem (hw.em.rxd in loader.conf). >> >> Adding lagg still results in a panci, but with your latest >> "return()"-patch, it's different: >> >> 0xffffffff8042aefb is in freebsd_generic_rx_handler … >> >> > Yeah, the same bug jist slipped back.

This patch avoids the panic :-) But unfortunately kills lagg (existing sockets break, nothing more tested yet) 488.896454 [ 394] nm_os_generic_find_num_desc called, in tx 1024 rx 1024 488.903445 [ 402] nm_os_generic_find_num_queues called, in txq 0 rxq 0 488.910424 [1252] generic_netmap_attach Created generic NA 0xfffff80036b26400 (prev 0) 488.971772 [ 448] generic_netmap_register Generic adapter 0xfffff80036b26400 goes on 488.980127 [ 495] generic_netmap_register RX ring 0 of generic adapter 0xfffff80036b26400 goes on 488.989917 [ 495] generic_netmap_register RX ring 1 of generic adapter 0xfffff80036b26400 goes on 488.999720 [ 502] generic_netmap_register TX ring 0 of generic adapter 0xfffff80036b26400 goes on 489.009504 [ 502] generic_netmap_register TX ring 1 of generic adapter 0xfffff80036b26400 goes on 489.019802 [3055] netmap_transmit lagg0 drop mbuf requiring offloadings 490.579512 [3055] netmap_transmit lagg0 drop mbuf requiring offloadings 491.781780 [3055] netmap_transmit lagg0 drop mbuf requiring offloadings … Have a nice sunday, will try to find some time next week to do more investigation, must close for today, haven't even read the messages, just wanted to drop a note. thnaks, -harry _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
