Hello I've stability issue with my new intel SASUC8I [1] PCIe controller. It's a LSI 1068e based controller. After a few minutes with disk io (csup or scrub by example) my FreeBSD 8-stable (64bit) is "freezing" for a couple of minutes and I see a lot of error messages like:
Sep 17 03:10:03 gw kernel: mpt0: request 0xffffff80002bc3b0:48367 timed out for ccb 0xffffff00050a8000 (req->ccb 0xffffff00050a8000) Sep 17 03:10:03 gw kernel: mpt0: request 0xffffff80002bbb40:48368 timed out for ccb 0xffffff0004f81800 (req->ccb 0xffffff0004f81800) Sep 17 03:10:03 gw kernel: mpt0: completing timedout/aborted req 0xffffff80002bc3b0:48367 Sep 17 03:10:03 gw kernel: mpt0: completing timedout/aborted req 0xffffff80002bbb40:48368 Sep 17 03:10:03 gw kernel: mpt0: Timedout requests already complete. Interrupts may not be functioning It takes minutes to execute commands after the first timeout message. The whole OS is running on single raidz ZFS pool. I use 4x 2TB SpinPoint F4 EcoGreen HD204UI disks with fixed firmware [2]. The disks are connected with brand new adaptec cables. I already replaced a cable to disqualify a cable issue. smartctl looks ok. The system is working fine if I connect all 4 disk to the the onboard controller. Is this an known issue with this controller and the mpt driver? Is there an workaround? I hope someone can help me.
