> Has anyone else experienced ongoing hardware read errors with this > configuration? I've experienced the disk dropping the scsi bus and not responding to selection. 3.1-STABLE invalidated the disk pack, and the machine then hung (cf. PR#11697). I still get some errors when using 3.2-STABLE: ------------ ahc0: <Adaptec aic7890/91 Ultra2 SCSI adapter> rev 0x00 int a irq 16 on pci2.4.0 ahc0: Reading SEEPROM...done. ahc0: BIOS eeprom not present ahc0: aic7890/91 Wide Channel A, SCSI Id=7, 16/255 SCBs ahc0: Downloading Sequencer Program... 393 instructions downloaded [.... snip ....] da1 at ahc0 bus 0 target 1 lun 0 da1: <QUANTUM QM318000TD-SCA N1K0> Fixed Direct Access SCSI-2 device da1: Serial Number PCB=20-116002-05; HDA=321904650954 da1: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing Enabled da1: 17366MB (35566499 512 byte sectors: 255H 63S/T 2213C) [.... snip ....] Unexpected busfree.
