I am also seeing SCSI errors with "Ubuntu 10.04.1 LTS" module aic7xxx and linux 2.6.32-25-generic with an Adaptec AHA-2940UW, with termination set to "automatic".
I have read, elsewhere, the opinion that there exists an old and a new aic7xxx driver, where the old driver works well with older SCSI cards, but that the new driver is not so good working with older cards. With no devices attached to the SCSI bus, there are no error messages. The SCSI card, while talking to an HP ScanJet 4c, C2520B, fails in different modes, depending upon the configuration of the card. With the channel set to include wide negotiation, there is an infinite loop of scsi4: Someone reset channel A and with the channel set to avoid wide negotiation, there is an error message and "Dump Card State": scsi 4:0:14:0: Attempting to queue an ABORT message CDB: 0x12 0x0 0x0 0x0 0x24 0x0 scsi4: At time of recovery, card was not paused >>>>>>>>>>>>>>>>>> Dump Card State Begins <<<<<<<<<<<<<<<<< scsi4: Dumping Card State while idle, at SEQADDR 0x1ab Card was paused ACCUM = 0x0, SINDEX = 0x20, DINDEX = 0xa0, ARG_2 = 0x0 HCNT = 0x20 SCBPTR = 0x0 SCSISIGI[0xff]:(ACKI|REQI|BSYI|SELI|ATNI|MSGI|IOI|CDI) ERROR[0x0] SCSIBUSL[0xff] LASTPHASE[0x1]:(P_BUSFREE) SCSISEQ[0x12]:(ENAUTOATNP|ENRSELI) SBLKCTL[0x2]:(SELWIDE) SCSIRATE[0x0] SEQCTL[0x10]:(FASTMODE) SEQ_FLAGS[0xc0]:(NO_CDB_SENT|NOT_IDENTIFIED) SSTAT0[0x4]:(SDONE) SSTAT1[0x20]:(SCSIRSTI) SSTAT2[0x0] SSTAT3[0x0] SIMODE0[0x0] SIMODE1[0x84]:(ENSCSIPERR|ENSELTIMO) SXFRCTL0[0x80]:(DFON) DFCNTRL[0xc]:(DIRECTION|HDMAEN) DFSTATUS[0x50]:(MREQPEND|DFCACHETH) STACK: 0x197 0xe 0x197 0xe SCB count = 4 Kernel NEXTQSCB = 2 Card NEXTQSCB = 3 QINFIFO entries: 3 Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Sequencer SCB Info: 0 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 1 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 2 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 3 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 4 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 5 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 6 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 7 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 8 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 9 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 10 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 11 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 12 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 13 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 14 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] 15 SCB_CONTROL[0x0] SCB_SCSIID[0xff]:(TWIN_CHNLB|OID|TWIN_TID) SCB_LUN[0xff]:(SCB_XFERLEN_ODD|LID) SCB_TAG[0xff] Pending list: 3 SCB_CONTROL[0x40]:(DISCENB) SCB_SCSIID[0xe7]:(TWIN_CHNLB) SCB_LUN[0x0] Kernel Free SCB list: 1 0 Untagged Q(14): 3 <<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>> scsi4:0:14:0: Cmd aborted from QINFIFO aic7xxx_abort returns 0x2002 and ending sometimes additionally with: scsi 4:0:15:0: Device offlined - not ready after error recovery or scsi4: Someone reset channel A -- aic7xxx module bug - aic7xxx_abort returns 0x2002 https://bugs.launchpad.net/bugs/610258 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
