https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236659 Bug ID: 236659 Summary: kernel page fault panic when chelsio cxgbei iscsi offload engine is enabled in ctld Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: freebsd-bugs@virtualtec.ch Created attachment 203000 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D203000&action= =3Dedit core.txt I'm setting up an HP DL380 G7 with a Chelsio T520-CR card as a zfs iscsi storage server. The server is connected multipath with a vsphere 5.5 test server. After a while with iSCSI traffic,= the freebsd server panics. It seems to be caused by a certain time of operation, not primarily by the amount of traffic, since I can frequently finish one run of CrystalMark on a VM on the vsphere server before I get the panic. Also, just keeping the server idle (but with the vsphere server reconnecting after the crash) can cause the panic a= fter 20-30min of uptime.=20 I'm only seeing the panic when I enable "offload cxgbei" in the ctl.conf portal-group, just having toe enabled on the interfaces will not cause the panic (at least not in the timeframe I monito= red the server). The server crashes whether I have dev.t5nex.0.toe.ddp enabled or not (it's currently enabled, it was originally not). These are configuration settings: /etc/rc.conf: ifconfig_cxl0=3D"mtu 9000 toe up" ifconfig_cxl1=3D"mtu 9000 toe up" cloned_interfaces=3D"vlan1513 vlan1514" # scsi-a ifconfig_vlan1513=3D"inet 10.140.3.2/24 vlan 1513 vlandev cxl0 up" # iscsi-b ifconfig_vlan1514=3D"inet 10.140.4.2/24 vlan 1514 vlandev cxl1 up" ctld_enable=3D"YES" # CAM Target Layer / iSCSI target daemon. kld_list=3D"t5fw_cfg if_cxl t4_tom cxgbei" /etc/ctl.conf: portal-group pg0 { discovery-auth-group no-authentication listen 10.140.3.2 listen 10.140.4.2 offload cxgbei } --=20 You are receiving this mail because: You are the assignee for the bug.=
