--vGgW1X5XWziG23Ko Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi. Got some new machines running 11.0-RELEASE-p8 with a small pile of SSD= in them. Getting some strange CAM timeouts at boot, that dramatically delay startup times. These errors don't happen at all after boot, everything seems just fine. Any clues / tuning suggestions are appreciated. Relevant stuff from dmesg: mpr0: <Avago Technologies (LSI) SAS3008> port 0x3000-0x30ff mem 0x92000000= -0x9200ffff,0x91f00000-0x91ffffff at device 0.0 numa-domain 0 on pci3 mpr0: IOCFacts : MsgVersion: 0x205 HeaderVersion: 0x2a00 IOCNumber: 0 IOCExceptions: 0x0 MaxChainDepth: 128 NumberOfPorts: 1 RequestCredit: 9680 ProductID: 0x2221 IOCRequestFrameSize: 32 MaxInitiators: 0 MaxTargets: 544 MaxSasExpanders: 125 MaxEnclosures: 126 HighPriorityCredit: 124 MaxReplyDescriptorPostQueueDepth: 65504 ReplyFrameSize: 32 MaxVolumes: 0 MaxDevHandle: 677 MaxPersistentEntries: 240 mpr0: Firmware: 13.00.00.00, Driver: 13.01.00.00-fbsd mpr0: IOCCapabilities: 7a85c<ScsiTaskFull,DiagTrace,SnapBuf,EEDP,TransRetr= y,EventReplay,MSIXIndex,HostDisc> da0 at mpr0 bus 0 scbus0 target 19 lun 0 da0: <ATA SAMSUNG MZ7KM960 GB32> Fixed Direct Access SPC-4 SCSI device da0: Serial Number S2HTNX0H701448 =20 da0: 1200.000MB/s transfers da0: Command Queueing enabled da0: 915715MB (1875385008 512 byte sectors) da0: quirks=3D0x8<4K> mpr0: Sending reset from mprsas_send_abort for target ID 19 mpr0: Unfreezing devq for target ID 19 (da0:mpr0:0:19:0): READ(10).
