https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258551 Bug ID: 258551 Summary: e1000: "Rework em_msi_link interrupt filter" commit causes to hard lock-up Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: t_uemura@macome.co.jp Created attachment 227954 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D227954&action= =3Dedit Successful boot sequence https://cgit.freebsd.org/src/commit/sys/dev/e1000?h=3Dstable/13&id=3D1fb96c= 59b4ce265ea94eddef5a97c7c075ceaec5 On my Shuttle DS77U Bhyve host, the above mentioned 1fb96c59b4ce265ea94eddef5a97c7c075ceaec5 commit causes the system to freeze during boot. Just backing out the commit solves. The detail is as follows. * Yesterday's 13-STABLE (8895170347fcfd9c9acf413ed408f11b15760b4b) * uname -a FreeBSD fwina.tesla.local 13.0-STABLE FreeBSD 13.0-STABLE #0: Thu Sep 16 18:42:17 JST 2021=20=20=20=20 root@fwina.tesla.local:/usr/obj/usr/src/amd64.amd64/sys/FWINA amd64 * Part of pciconf -lv: em0@pci0:0:31:6: class=3D0x020000 rev=3D0x21 hdr=3D0x00 vendor=3D0x8= 086 device=3D0x156f subvendor=3D0x8086 subdevice=3D0x0000 vendor =3D 'Intel Corporation' device =3D 'Ethernet Connection I219-LM' class =3D network subclass =3D ethernet igb0@pci0:1:0:0: class=3D0x020000 rev=3D0x03 hdr=3D0x00 vendor=3D0= x8086 device=3D0x1539 subvendor=3D0x1297 subdevice=3D0x4052 vendor =3D 'Intel Corporation' device =3D 'I211 Gigabit Network Connection' class =3D network subclass =3D ethernet * Live LAN connection hooked up only to igb0. em0 has no connection during test. * bridge is fabricated because this host also serves as a traffic filter. autobridge_interfaces=3D"bridge0" autobridge_bridge0=3D"igb0 em0" cloned_interfaces=3D"bridge0" ifconfig_bridge0=3D"up" ifconfig_em0=3D"up" ifconfig_igb0=3D"inet 10.141.30.22 netmask 255.255.255.0 up" * Various modules specified in $devmatch_blacklist so no kld is loaded duri= ng test. When the mentioned commit backed out, the system boots without any glitch. = When the commit being applied, the system freezes at adding net default: gateway, maybe trying to link up the bridge0 and its member interfaces. The attached ok.jpg shows the successful activation of bridge0 while the ng= .jpg is the capture of the hard lock-up. Power-cycle, load the previous kernel a= nd fsck is the only available option to recover. --=20 You are receiving this mail because: You are the assignee for the bug.=
