Re: Troubles with USB

I finally had some time today to get back to this.

In the end, I traced the problem with USB drives to the RAM upgrade I
performed. Pulling out the extra 8GB I added and leaving the machine with
2GB made the USB drives work again and I could reinstall the system. I'm
not sure why my previous attempt at doing this failed.

This smells like a bug in FreeBSD to me though. OpenFirmware had no trouble
loading the kernel and booting it but FreeBSD was just confused reading
from the drives. In fact, if I booted the already-installed FreeBSD,
plugged the USB stick in, and ran a "dd" to read the data, all I got were
zeroes. And if I tried to unplug and replug the drive, the system would
hang.
