--- Comment #11 from Sean Bruno <sbr...@freebsd.org> --- Did a couple of tests via iperf. test 1 #1 set hw.em.txd="4096" #2 set hw.em.rxd="4096" #3 ran with TSO enabled -- ran into hangs and debug output from watchdog as reporter and stated. -- seems to happen less frequently, once in 24 hour test test 2 #1 setup as test 1 #2 disable TSO (ifconfig em0 -tso) -- no hangs in 24 hours test test 3 #1 set hw.em.txd="256" #2 set hw.em.rxd="256" #3 reboot and leave TSO enabled -- ran into hangs and debug out from watchdog in minutes Hypothesis: -- TSO implementation isn't taking into consideration ring wrap events? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
