https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221845 --- Comment #3 from Russell Haley <russ.haley@gmail.com> --- I've been following the code through and wound up at sys/arm/ti/cpsw/if_cps= w.c. cpsw_intr_rx is defined on line 1554. The function uses a macro called CPSW_RX_LOCK which is defined on line 349. The macro contains an assert on a transmit lock (tx.lock). I theorise the statement on line 350 is causing my exception? I also wonder if the lock being held between lines 1561 and 1570= is causing the delay in the bridge interface that is causing the original post= ers' slow throughput. Is it necessary to hold the lock until after the cpsw_writ= e_4 on line 1569 or could it be performed outside the lock? --=20 You are receiving this mail because: You are the assignee for the bug.=
