hi, i'm using 4.8-release[1] and experienced a similar problem last week using the same scsi-adapter[2] and the same drive[3]: my system froze during boottime just like yours. it stopped after detecting the dnes-309170w. i've successfully tested the controller, the cable and the termination with another scsi-drive[4]. desperate as i was i decided to low-level format the "broken" drive via the controllers buildin scsi-tools ... the drive got detected afterwards and is up and running since then. - worldi [1] %uname -srm FreeBSD 4.8-RELEASE-p13 i386 [2] ahc0: <Adaptec 2940 Ultra2 SCSI adapter> port 0xa800-0xa8ff mem 0xed001000-0xed001fff irq 11 at device 9.0 on pci0 [3] da0 at ahc0 bus 0 target 0 lun 0 da0: <IBM DNES-309170W SAH0> Fixed Direct Access SCSI-3 device da0: 80.000MB/s transfers (40.000MHz, offset 30, 16bit), Tagged Queueing Enabled da0: 8748MB (17916240 512 byte sectors: 255H 63S/T 1115C) [4] da1 at ahc0 bus 0 target 1 lun 0 da1: <IBM DDRS-39130W S97B> Fixed Direct Access SCSI-2 device da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da1: 8715MB (17850000 512 byte sectors: 255H 63S/T 1111C) -- Look what has become of your world... > [not subscribed to -scsi, if OT for stable please keep me in > Mail-Followup-To:] > > Hi, > > I can hang my system at will reading from my SCSI CD-RW.
