https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256305 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. 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 most recent software. Here's a sysctl dump of the device. 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: 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 Channel 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=0x10df device=0xe300 subvendor=0x10df subdevice=0xe310 class=0x0c0400 dev.ocs_fc.0.%location: slot=0 function=0 dbsf=pci0:59:0:0 handle=\_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=0x0c0400 card=0xe31010df chip=0xe30010df rev=0x01 hdr=0x00 vendor = 'Emulex Corporation' device = 'LPe31000/LPe32000 Series 16Gb/32Gb Fibre Channel Adapter' class = serial bus subclass = Fibre Channel If there is any other information you need, let me know.
