https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D257670 Bug ID: 257670 Summary: RAS CONTROLLER: Fatal unrecoverable error detected with SAS3008 Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: daniel@morante.net Attachment #227004 text/plain mime type: Created attachment 227004 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D227004&action= =3Dedit capture of boot via serial I am testing FreeBSD-14.0-CURRENT-arm64-aarch64-20210805-f3a3b061216-248478= on a Cavium ThunderX2 (Gigabyte R281-T91). This system has an onboard SAS3008 PCI-Express Fusion-MPT SAS-3 controller.=20=20 ``` mpr0@pci0:14:0:0: class=3D0x010700 rev=3D0x02 hdr=3D0x00 vendor=3D0x1= 000 device=3D0x0097 subvendor=3D0x1458 subdevice=3D0x3008 vendor =3D 'Broadcom / LSI' device =3D 'SAS3008 PCI-Express Fusion-MPT SAS-3' class =3D mass storage subclass =3D SAS ``` I load the `mpr` driver by having `mpr_load=3D"YES"` in `/boot/loader.conf`= . So far so good except for the weird messages in dmesg. (see attachment) There are currently 8 HDD's attached to it and I setup 3 ZFS pools. This g= oes well until I finally start to put some load on them. The system kernel pan= ics and halts with the following in dmesg: ``` mpr0: IOC Fault 0x4000265d, Resetting mpr0: Reinitializing controller ... RAS CONTROLLER: Fatal unrecoverable error detected ``` This is not to say the problem is with ZFS. I suspect the mpr driver is ju= st unstable. The system can no longer boot into multi user mode. It kernel panics with = the same error as soon as it tries to start ZFS. ``` mountroot: waiting for device /dev/nda0p2... WARNING: / was not properly dismounted Dual Console: Video Primary, Serial Secondary witness_lock_list_get: witness exhausted ZFS filesystem version: 5 ZFS storage pool version: features support (5000) RAS CONTROLLER: Fatal unrecoverable error detected *** NBU Error *** ... ``` In order to get a functional system I disable ZFS in `/etc/rc.conf` while in single user mode. Now back in multi user mode I can do a `service zfs onestart` and try to im= port one of the pools. The system then kernel panics again. I detail the full specs of this system in bug #254651 (where I have a probl= em with the onboard SATA controllers) and in my forum post at https://forums.freebsd.org/threads/aarch64-trouble-with-cn99xx-ahci-and-fas= tlinq-ql41000-controllers.79556/ (where I explain the lack of a driver for the onboard Ethernet). Also, for some weird reason I can no longer boot 13.0-RELEASE on this syste= m.=20 It panics with "panic: NVME polled command failed to complete within 10s". I think it doesn't like the add-on PCIe NVME. However when it was working (p= rior to adding in the NVME) the SAS controller was just as unstable. Seeing how most of the hardware is still very new, I don't expect FreeBSD (especcially arm64) to support it. I'd like to help anyway that I can shou= ld someone be interested. The system has an IPMI and I'd be willing to offer remote access to it for as long as it's required via VPN (if that's a thing that's normally done) on a dedicated network with any other required resources). --=20 You are receiving this mail because: You are the assignee for the bug.=
