We recently changed out this card (32-bit card, one channel): 10:14.0 SCSI storage controller: LSI Logic / Symbios Logic (formerly NCR) 53c895 (rev 02) Subsystem: LSI Logic / Symbios Logic (formerly NCR): Unknown device 1020 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- rev 0x2 on pci bus 16 device 20 function 0 irq 54 sym0: No NVRAM, ID 7, Fast-40, LVD, parity checking sym0: SCSI BUS has been reset. scsi2 : sym-2.1.17a For this one (64-bit PCI card, with 2 channels) 10:14.0 SCSI storage controller: LSI Logic / Symbios Logic (formerly NCR) 53c1010 Ultra3 SCSI Adapter (rev 01) Subsystem: LSI Logic / Symbios Logic (formerly NCR): Unknown device 1030 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr+ Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR- TAbort- SERR- rev 0x1 on pci bus 16 device 20 function 0 irq 54 sym0: No NVRAM, ID 7, Fast-80, LVD, parity checking sym0: SCSI BUS has been reset. sym1: <1010-33> rev 0x1 on pci bus 16 device 20 function 1 irq 54 sym1: No NVRAM, ID 7, Fast-80, SE, parity checking sym1: SCSI BUS has been reset. sym1: SCSI BUS mode change from SE to SE. scsi2 : sym-2.1.17a scsi3 : sym-2.1.17a The old card was attached to our SEAGATE Model: ULTRIUM06242-XXX Rev: 1470 for nightly backups. The backups ran fine. After attaching the tape drive to the new card, during the backup we get this: sym0:6: ERROR (40:0) (0-20-0) (1f/18/0) @ (scripta ad8:10001e00). sym0: script cmd = 10000000 sym0: regdump: da 10 c0 18 47 1f 06 0a 00 00 86 20 80 01 08 01 00 ac c7 1e 08 00 00 00. sym0: PCI STATUS = 0x8100 sym0: SCSI BUS reset detected. sym0: SCSI BUS has been reset. st0: Error 80000 (sugg. bt 0x0, driver bt 0x0, host bt 0x8). st0: Error with sense data: Current st09:00: sense key Unit Attention Additional sense indicates Power on,reset,or bus device reset occurred st0: Error on write filemark. The system is a powerpc G4 SMP @533mhz, with 1G of ram. We're using kernel-2.4.20, SMP, and HIMEM enabled. Termination and cabling are definately correct. We tried the sym53c8xx module with both 32 and 40 bit DMA addressing.. same results.. the old card works fine, the new card causes these errors and the backup aborts. We'd definately rather use the new 2 channel card, as we'd like to attach a disk to the other channel.. but this is preventing us from doing it. Any ideas? I'm up for trying anything here to get this to work. thanks, Ethan Weinstein
