https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D256305 Bug ID: 256305 Summary: ocs_fc - panic: ffs_blkfree_cg: freeing free block Product: Base System Version: 12.2-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dave@jetcafe.org I am running FreeBSD 12.2-STABLE r368820 amd64. We are getting this panic on our storage SAN which we access via the ocs_fc driver. It appears to be triggered by high I/O rates; specifically if we run between 5 and 10 dd commands reading and writing to this unit OR if we try = to backup large files to this SAN. If we repeat our tests on 11.3, it's fine and no crashes happen.=20 The driver is identified by the kernel as: ocs_fc0: <Emulex LightPulse FC Adapter> mem 0xab088000-0xab08ffff,0xab110000-0xab110fff at device 0.0 numa-domain 0 on = pci8 The card has the most recent firmware available, and the SAN also has the m= ost recent software. Here's a sysctl dump of the device.=20 dev.ocs_fc.0.port_state: online dev.ocs_fc.0.fcid: 0x043480 dev.ocs_fc.0.businfo: 3B:00:00 dev.ocs_fc.0.configured_speed: 0 dev.ocs_fc.0.configured_topology: 0 dev.ocs_fc.0.current_speed: 16000 dev.ocs_fc.0.current_topology: 1 dev.ocs_fc.0.wwpn: 0x100000109b4ab93b dev.ocs_fc.0.wwnn: 0x200000109b4ab93b dev.ocs_fc.0.fw_upgrade:=20 dev.ocs_fc.0.sli_intf: c0022c40 dev.ocs_fc.0.fwrev: 12.8.351.32, sli-4:2:c dev.ocs_fc.0.sn: FC82553901 dev.ocs_fc.0.modeldesc: Emulex LightPulse LPe31002-M6 2-Port 16Gb Fibre Cha= nnel Adapter dev.ocs_fc.0.devid: 3808432351 dev.ocs_fc.0.%domain: 0 dev.ocs_fc.0.%parent: pci8 dev.ocs_fc.0.%pnpinfo: vendor=3D0x10df device=3D0xe300 subvendor=3D0x10df subdevice=3D0xe310 class=3D0x0c0400 dev.ocs_fc.0.%location: slot=3D0 function=3D0 dbsf=3Dpci0:59:0:0 handle=3D\_SB_.PC02.BR2A.UPS_ dev.ocs_fc.0.%driver: ocs_fc dev.ocs_fc.0.%desc: Emulex LightPulse FC Adapter pciconf has this: ocs_fc0@pci0:59:0:0: class=3D0x0c0400 card=3D0xe31010df chip=3D0xe30010d= f rev=3D0x01 hdr=3D0x00 vendor =3D 'Emulex Corporation' device =3D 'LPe31000/LPe32000 Series 16Gb/32Gb Fibre Channel Adapte= r' class =3D serial bus subclass =3D Fibre Channel If there is any other information you need, let me know.
