https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D252626 Bug ID: 252626 Summary: ixl: panic on attach of X722 on-motherboard interfaces Product: Base System Version: 12.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: wollman@FreeBSD.org I upgraded our fleet of ~20 NFS servers today from 12.1 to 12.2-RELEASE-p2. Three of the newest servers, which have X722 interfaces on the motherboard, crash at attach time with the following trace: --- trap 0xc, rip =3D 0xffffffff80757efd, rsp =3D 0xfffffe0075dff2d0, rbp = =3D 0xfffffe0075dff2e0 --- grouptaskqueue_enqueue() at grouptaskqueue_enqueue+0xd/frame 0xfffffe0075df= f2e0 ixl_admin_timer() at ixl_admin_timer+0x11/frame 0xfffffe0075dff300 softclock_call_cc() at softclock_call_cc+0x141/frame 0xfffffe0075dff3b0 softclock() at softclock+0x79/frame 0xfffffe0075dff3d0 ithread_loop() at ithread_loop+0x23c/frame 0xfffffe0075dff430 fork_exit() at fork_exit+0x7e/frame 0xfffffe0075dff470 fork_trampoline() at f (There's an omitted frame where ixl_admin_timer() calls iflib_admin_intr_deferred() -- apparently pf->vsi.ctx is not initialized ye= t, or there's a missing memory barrier?) The problem is not observed on older servers with X710 interfaces. (We don= 't use the 1G interfaces for anything, and if we didn't have servers that need= it, I would just yank ixl(4) from our standard kernel configuration. I might s= till do that and just load the module on the three servers that need it.) The systems that panic have: ixl0@pci0:26:0:0: class=3D0x020000 card=3D0x37d115d9 chip=3D0x37d1808= 6 rev=3D0x09 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Ethernet Connection X722 for 1GbE' class =3D network subclass =3D ethernet The systems that boot (and operate properly) have: ixl0@pci0:3:0:0: class=3D0x020000 card=3D0x00088086 chip=3D0x1572808= 6 rev=3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'Ethernet Controller X710 for 10GbE SFP+' class =3D network subclass =3D ethernet --=20 You are receiving this mail because: You are the assignee for the bug.=
