https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235342 Bug ID: 235342 Summary: [em] em0 hangs when vnet jail starts while transferring files Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: naito.yuichiro@gmail.com I'm using "FreeBSD 13.0-CURRENT r343486 GENERIC-NODEBUG amd64" with following NIC. em0@pci0:0:31:6: class=0x020000 card=0x00008086 chip=0x15b78086 rev=0x31 hdr=0x00 vendor = 'Intel Corporation' device = 'Ethernet Connection (2) I219-LM' class = network subclass = ethernet A following scenario causes em driver hangs. 1. start file transfer through em0. I used sftp or netatalk. Both of them causes same result. 2. start vnet jail while transferring the file. I used iocage with vnet=on dhcp=on bpf=yes. Without iocage using jail.conf causes same result. 3. "em0: TX(0) desc avail = 1024, pidx = 0" is shown on console repetitive and infinitely. After 3., em0 hangs and no packets can be sent and/or received. ifconfig up/down won't recover this hang up. I've tried my jail with iocage set vnet=on dhcp=off bpf=no, Nothing changed. Upgrading to 'FreeBSD 13.0-CURRENT r343598 GENERIC-NODEBUG amd64' won't fix this problem. Workaround is installing net/intel-em-kmod for now. -- You are receiving this mail because: You are the assignee for the bug.help
