[-- Attachment #1 --] On a relatively old test machine, dual-socket X7DWU supermicro, Xeon X5272, with on-board 82575EB igb controllers, running the stress2 udp blast test immediately causes the following panic: buf=0xfffff8001aa5c800 already enqueue at 1445 prod=1315 cons=1445 cpuid = 3 KDB: stack backtrace: db_trace_self_wrapper() at 0xffffffff802839ab = db_trace_self_wrapper+0x2b/frame 0xfffffe0123570600 vpanic() at 0xffffffff8033bd96 = vpanic+0x126/frame 0xfffffe0123570640 panic() at 0xffffffff8033be23 = panic+0x43/frame 0xfffffe01235706a0 igb_mq_start() at 0xffffffff80bcb228 = igb_mq_start+0xb8/frame 0xfffffe0123570710 ether_output() at 0xffffffff804072a8 = ether_output+0x5c8/frame 0xfffffe0123570780 ip_output() at 0xffffffff80430be1 = ip_output+0xe91/frame 0xfffffe0123570860 udp_send() at 0xffffffff804a5fc4 = udp_send+0x834/frame 0xfffffe0123570910 sosend_dgram() at 0xffffffff803b517b = sosend_dgram+0x36b/frame 0xfffffe0123570990 soo_write() at 0xffffffff8039dbb9 = soo_write+0x49/frame 0xfffffe01235709d0 dofilewrite() at 0xffffffff803956c5 = dofilewrite+0x85/frame 0xfffffe0123570a20 kern_writev() at 0xffffffff803953d5 = kern_writev+0x65/frame 0xfffffe0123570a70 sys_write() at 0xffffffff80395363 = sys_write+0x63/frame 0xfffffe0123570ac0 amd64_syscall() at 0xffffffff8053ae7d = amd64_syscall+0x28d/frame 0xfffffe0123570bf0 Test is available at svn:base/user/pho/stress2/testcases/udp, invocation line is BLASTHOST=192.168.5.1 ./udp -t 10m -i 50 -h -v Substitute the BLASTHOST with the ip address of a scratch box. This is on the yesterday HEAD. Could you, please, fix this ?
