I thank those that helped, via the mailing lists, and at tonights OCUUG <http://www.ocuug.on.ca/>; meeting. We spent some time looking at the differences between the 4.10 and 5.3 code to see if we could track down the issue. We gave up when the pizza arrived.... There were While there, we tried the EXAR MEDIA JUMPDRIVE ELITE, rev 2.00/20.00 on: 4.10 - failed as previously mentioned 5.3 - worked NetBSD -current from about 2 months ago - worked I also tried two other USB HDDs supplied by David Maxwell and Diane Bruce. Both worked under 4.10. On the way home from the meeting, I returned the Lexar and purchased a Kingston Data Traveller (KUSBDTI/512CR), which I'm pleased to say works under 4.10/ Dec 9 21:22:17 laptop /kernel: umass0: Kingston DataTraveler 2.0, rev 2.00/1.00, addr 2 Dec 9 21:22:17 laptop /kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Dec 9 21:22:17 laptop /kernel: da0: <Kingston DataTraveler 2.0 6.00> Removable Direct Access SCSI-2 device Dec 9 21:22:17 laptop /kernel: da0: 650KB/s transfers Dec 9 21:22:17 laptop /kernel: da0: 489MB (1001472 512 byte sectors: 64H 32S/T 489C) And under 5.3: Dec 9 21:27:25 laptop kernel: umass0: Kingston DataTraveler 2.0, rev 2.00/1.00, addr 2 Dec 9 21:27:25 laptop kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Dec 9 21:27:25 laptop kernel: da0: <Kingston DataTraveler 2.0 6.00> Removable Direct Access SCSI-2 device Dec 9 21:27:25 laptop kernel: da0: 1.000MB/s transfers Dec 9 21:27:25 laptop kernel: da0: 489MB (1001472 512 byte sectors: 64H 32S/T 489C) Note the faster speed under 5.3 (1MB vs 650K) Interestingly enough, I was able to panic both 5.3 and 4.10 by removing the USB device at the "wrong" time. I am unable to say just when that is. Sometimes it just happened. cheers -- Dan Langille : http://www.langille.org/ BSDCan - The Technical BSD Conference - http://www.bsdcan.org/
