Hi fellows. I've recently installed FreeBSD-5.3-RELEASE at my 3.0 GHz Intel Pentium Server with Adaptec SCSI controllers and a couple of Seagate U-SCSI320 hard disks. After re-compiling the kernel with support of ipfw and smp, dmesg shows the following warnings. ---- begin of dmesg output ---- Waiting 15 seconds for SCSI devices to settle ahd0: Invalid Sequencer interrupt occurred. >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< ahd0: Dumping Card State at program address 0x235 Mode 0x0 Card was paused INTSTAT[0x0] SELOID[0x1] SELID[0x0] HS_MAILBOX[0x0] INTCTL[0x80]:(SWTMINTMASK) SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x33]:(CURRFIFO_NONE|FIFO0FREE|FIFO1FREE) SCSISIGI[0x0]:(P_DATAOUT) SCSIPHASE[0x0] SCSIBUS[0x0] LASTPHASE[0x1]:(P_DATAOUT|P_BUSFREE) SCSISEQ0[0x0] SCSISEQ1[0x12]:(ENAUTOATNP|ENRSELI) SEQCTL0[0x0] SEQINTCTL[0x6]:(INTMASK1|INTMASK2) SEQ_FLAGS[0x0] SEQ_FLAGS2[0x0] QFREEZE_COUNT[0x2] KERNEL_QFREEZE_COUNT[0x2] MK_MESSAGE_SCB[0xff00] MK_MESSAGE_SCSIID[0xff] SSTAT0[0x0] SSTAT1[0x0] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0x0] SIMODE1[0xa4]:(ENSCSIPERR|ENSCSIRST|ENSELTIMO) LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x0] SCB Count = 16 CMDS_PENDING = 0 LASTSCB 0xffff CURRSCB 0xf NEXTSCB 0xff40 qinstart = 31 qinfifonext = 31 QINFIFO: WAITING_TID_QUEUES: Pending list: Total 0 Kernel Free SCB list: 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 0 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: Sequencer On QFreeze and Complete list: ahd0: FIFO0 Free, LONGJMP == 0x8000, SCB 0x1 SEQIMODE[0x3f]:(ENCFG4TCMD|ENCFG4ICMD|ENCFG4TSTAT|ENCFG4ISTAT|ENCFG4DATA|ENSAVEPTRS) SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89]:(FIFOEMP|HDONE|PRELOAD_AVAIL) SG_CACHE_SHADOW[0x2]:(LAST_SEG) SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5]:(FIFOFREE|DLZERO) SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10]:(SG_CACHE_AVAIL) ahd0: FIFO1 Free, LONGJMP == 0x8063, SCB 0xf SEQIMODE[0x3f]:(ENCFG4TCMD|ENCFG4ICMD|ENCFG4TSTAT|ENCFG4ISTAT|ENCFG4DATA|ENSAVEPTRS) SEQINTSRC[0x0] DFCNTRL[0x0] DFSTATUS[0x89]:(FIFOEMP|HDONE|PRELOAD_AVAIL) SG_CACHE_SHADOW[0x2]:(LAST_SEG) SG_STATE[0x0] DFFSXFRCTL[0x0] SOFFCNT[0x0] MDFFSTAT[0x5]:(FIFOFREE|DLZERO) SHADDR = 0x00, SHCNT = 0x0 HADDR = 0x00, HCNT = 0x0 CCSGCTL[0x10]:(SG_CACHE_AVAIL) LQIN: 0x8 0x0 0x0 0x1 0x0 0x4 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 ahd0: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x42 ahd0: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x1 ahd0: SAVED_SCSIID = 0x0 SAVED_LUN = 0x0 SIMODE0[0xc]:(ENOVERRUN|ENIOERR) CCSCBCTL[0x4]:(CCSCBDIR) ahd0: REG0 == 0xc160, SINDEX = 0x180, DINDEX = 0x104 ahd0: SCBPTR == 0x1, SCB_NEXT == 0xff40, SCB_NEXT2 == 0xff29 CDB 12 80 0 80 88 b1 STACK: 0x230 0x1 0x0 0x0 0x0 0x0 0x0 0x0 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> Copied 18 bytes of sense data offset 12: 0x70 0x0 0x6 0x0 0x0 0x0 0x0 0xa 0x0 0x0 0x0 0x0 0x29 0x2 0x2 0x0 0x0 0x0 Copied 18 bytes of sense data offset 12: 0x70 0x0 0x6 0x0 0x0 0x0 0x0 0xa 0x0 0x0 0x0 0x0 0x29 0x2 0x2 0x0 0x0 0x0 SMP: AP CPU #1 Launched! da0 at ahd0 bus 0 target 0 lun 0 da0: <SEAGATE ST336607LW 0007> Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz, offset 63, 16bit), Tagged Queueing Enabled da0: 35003MB (71687372 512 byte sectors: 255H 63S/T 4462C) da1 at ahd0 bus 0 target 1 lun 0 da1: <SEAGATE ST336607LW 0007> Fixed Direct Access SCSI-3 device da1: 320.000MB/s transfers (160.000MHz, offset 63, 16bit), Tagged Queueing Enabled da1: 35003MB (71687372 512 byte sectors: 255H 63S/T 4462C) ---- end of dmesg output ---- As u can see both of HDD's are launched successfully, and I didn't notice any malfunction in system.
