I'm working with 5.0-REL. Using a pair of AHA29160s, if I e.g. reset the bus from the initiator after enabling a lun on the target, I get on the target: Infinite interrupt loop, INTSTAT = 0(targ0:ahc1:0:0:0): SCB 0xe - timed out ahc1: Dumping Card State while idle, at SEQADDR 0x18 ACCUM = 0xe, SINDEX = 0xfa, DINDEX = 0xe4, ARG_2 = 0x3 HCNT = 0x0 SCBPTR = 0x0 SCSISIGI[0x48]:(SELI|IOI) SCSIPHASE[0x0] SCSIBUSL[0x0] LASTPHASE[0x1]:(P_BUSFREE) SCSISEQ[0xba]:(ENAUTOATNP|ENAUTOATNO|ENRSELI|ENSELI|TEMODE) SBLKCTL[0xa]:(SELWIDE|SELBUSB) SEQCTL[0x10]:(FASTMODE) SEQ_FLAGS[0xc0]:(NO_CDB_SENT|NOT_IDENTIFIED) SSTAT0[0x90]:(SELINGO|TARGET) SSTAT1[0x0] SSTAT2[0x0] SSTAT3[0x0] SIMODE0[0x8]:(ENSWRAP) SIMODE1[0xac]:(ENSCSIPERR|ENBUSFREE|ENSCSIRST|ENSELTIMO) SXFRCTL0[0x80]:(DFON) DFCNTRL[0x0] DFSTATUS[0x89]:(FIFOEMP|HDONE|PRELOAD_AVAIL) STACK: 0x4 0x3 0x166 0x17 SCB count = 20 Kernel NEXTQSCB = 15 Card NEXTQSCB = 15 QINFIFO entries: Waiting Queue entries: 0:14 Disconnected Queue entries: QOUTFIFO entries: <sequencer dump snipped> any ideas? thanks john
