So i still get the below card state dump CB time out messages with tags forced to 32. I'm pursuing this with Seagate, but I'll ask again... is this a bug with either the AIC7902, or the driver for it, or the cam layer, or something? The AIC7902 is: card=0x005f9005 chip=0x801f9005 # camcontrol devlist <SEAGATE ST318453LW 0005> at scbus0 target 0 lun 0 (pass0,da0) # camcontrol tags 0:0:0 (pass0:ahd0:0:0:0): device openings: 32 # camcontrol inq 0:0:0 pass0: <SEAGATE ST318453LW 0005> Fixed Direct Access SCSI-3 device pass0: Serial Number 3JY0FVNT00007343D27D pass0: 320.000MB/s transfers (160.000MHz, offset 63, 16bit), Tagged Queueing Enabled (da0:ahd0:0:0:0): SCB 0x1a - timed out >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< ahd0: Dumping Card State at program address 0x27 Mode 0x22 Card was paused HS_MAILBOX[0x0] INTCTL[0xc0]:(SWTMINTEN|SWTMINTMASK) SEQINTSTAT[0x0] SAVED_MODE[0x11] DFFSTAT[0x31]:(CURRFIFO_1|FIFO0FREE|FIFO1FREE) SCSISIGI[0x0]:(P_DATAOUT) SCSIPHASE[0x0] SCSIBUS[0x0] LASTPHASE[0x1]:(P_DATAOUT|P_BUSFREE) SCSISEQ0[0x0] SCSISEQ1[0x12]:(ENAUTOATNP|ENRSELI) SEQCTL0[0x10]:(FASTMODE) SEQINTCTL[0x0] SEQ_FLAGS[0x0] SEQ_FLAGS2[0x0] SSTAT0[0x0] SSTAT1[0x0] SSTAT2[0x0] SSTAT3[0x0] PERRDIAG[0x8]:(AIPERR) SIMODE1[0xa4]:(ENSCSIPERR|ENSCSIRST|ENSELTIMO) LQISTAT0[0x0] LQISTAT1[0x0] LQISTAT2[0x0] LQOSTAT0[0x0] LQOSTAT1[0x0] LQOSTAT2[0x1]:(LQOSTOP0) SCB Count = 32 CMDS_PENDING = 14 LASTSCB 0x7 CURRSCB 0x7 NEXTSCB 0xff80 qinstart = 29946 qinfifonext = 29946 QINFIFO: WAITING_TID_QUEUES: Pending list: 7 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 1 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 24 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 27 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 18 FIFO_USE[0x0] SCB_CONTROL[0x62]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 31 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 10 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 20 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 28 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 4 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 17 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 21 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 25 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] 26 FIFO_USE[0x0] SCB_CONTROL[0x60]:(TAG_ENB|DISCENB) SCB_SCSIID[0x7] Total 14 Kernel Free SCB list: 16 30 19 15 13 11 8 9 5 2 23 29 0 14 6 3 22 12 Sequencer Complete DMA-inprog list: Sequencer Complete list: Sequencer DMA-Up and Complete list: ahd0: FIFO0 Free, LONGJMP == 0x80ff, SCB 0x4 SEQIMODE[0x3f]:(ENCFG4TCMD|ENCFG4ICMD|ENCFG4TSTAT|ENCFG4ISTAT|ENCFG4DATA|ENS AVEPTRS) 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 == 0x8257, SCB 0x1a SEQIMODE[0x3f]:(ENCFG4TCMD|ENCFG4ICMD|ENCFG4TSTAT|ENCFG4ISTAT|ENCFG4DATA|ENS AVEPTRS) 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: 0x55 0x0 0x0 0x1a 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x80 0x0 0x0 0x0 0x2 0x0 ahd0: LQISTATE = 0x0, LQOSTATE = 0x0, OPTIONMODE = 0x42 ahd0: OS_SPACE_CNT = 0x20 MAXCMDCNT = 0x1 SIMODE0[0xc]:(ENOVERRUN|ENIOERR) CCSCBCTL[0x4]:(CCSCBDIR) ahd0: REG0 == 0x7, SINDEX = 0x122, DINDEX = 0x102 ahd0: SCBPTR == 0x1, SCB_NEXT == 0x7, SCB_NEXT2 == 0xff34 CDB a 5 b1 9f 20 0 STACK: 0x15 0x125 0x0 0x0 0x257 0x257 0x240 0x29 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> swap_pager: indefinite wait buffer: device: #da/0x30001, blkno: 8536, size: 4096 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 Aug 6 16:53:22 /kernel: <<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> Message from syslogd@ at Wed Aug 6 16:53:22 2003 ... /kernel: <<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>>
