We've recently added a 3940W and some wide disks to our newsserver, and it has been panicking and trashing the disks on that controller about every two days since the disks were installed. Our kernel boot says: [. . .] Probing for devices on PCI bus 0: chip0 <Intel 82437 (Triton)> rev 1 on pci0:0 chip1 <Intel 82371 (Triton)> rev 2 on pci0:7 de0 <Digital DC21140 Fast Ethernet> rev 17 int a irq 12 on pci0:9 de0: DC21140 [10-100Mb/s] pass 1.1 Ethernet address 00:00:c0:86:f7:9d de0: enabling 10baseT UTP port ahc0 <Adaptec 2940 SCSI host adapter> rev 3 int a irq 10 on pci0:10 ahc0: aic7870 Single Channel, SCSI Id=7, 16 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "SEAGATE ST51080N 0943" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 1030MB (2109840 512 byte sectors) chip2 <DEC 21050 PCI-PCI bridge> rev 2 on pci0:11 Probing for devices on PCI bus 1: ahc1 <Adaptec 3940 Ultra SCSI host adapter> rev 0 int a irq 11 on pci1:4 ahc1: aic7880 Wide Channel A, SCSI Id=7, 255 SCBs ahc1 waiting for scsi devices to settle (ahc1:1:0): "Quantum XP34300W 81HB" type 0 fixed SCSI 2 sd1(ahc1:1:0): Direct-Access 4101MB (8399520 512 byte sectors) ahc2 <Adaptec 3940 Ultra SCSI host adapter> rev 0 int a irq 10 on pci1:5 ahc2: aic7880 Wide Channel B, SCSI Id=7, 255 SCBs ahc2 waiting for scsi devices to settle (ahc2:1:0): "Quantum XP34300W 81HB" type 0 fixed SCSI 2 sd2(ahc2:1:0): Direct-Access 4101MB (8399520 512 byte sectors) Probing for devices on the ISA bus: [. . .] The appropriate area of the kernel config file says: controller ncr0 options "SCSI_NCR_MAX_TAGS=0" #for that HP C3725 # ahc: Adaptec 274x/284x/294x, always: controller ahc0 #controller ahc1 at isa? bio irq ? vector ahcintr #form after 1/5/96 controller ahc1 controller ahc2 controller scbus0 device ch0 #SCSI media changers device sd0 #SCSI disks device st0 #SCSI tapes device cd0 #SCSI CD-ROMs We're running 2.1-STABLE.
